Homemade Chocolate Croissants Recipes

HOMEMADE CHOCOLATE CROISSANTS (PAIN AU CHOCOLATE) RECIPE BY TASTY

Steps:

• In a large bowl, mix the flour, water, milk, sugar, salt, yeast, and butter.
• Once the dough starts to clump, turn it out onto a clean counter.
• Lightly knead the dough and form it into a ball, making sure not to over-knead it.
• Cover the dough with plastic wrap and refrigerate for one hour.
• Slice the cold butter in thirds and place it onto a sheet of parchment paper..
• Place another piece of parchment on top of the butter, and beat it with a rolling pin.
• Keeping the parchment paper on the butter, use a rolling pin to roll the butter into a 7-inch (18 cm) square, ½-inch (1 cm) thick. If necessary, use a knife to trim the edges and place the trimmings back on top of the butter and continue to roll into a square.
• Transfer the butter layer to the refrigerator.
• To roll out the dough, lightly flour the counter. Place the dough on the counter, and push the rolling pin once vertically into the dough and once horizontally to form four quadrants.
• Roll out each corner and form a 10-inch (25 cm) square.
• Place the butter layer on top of the dough and fold the sides of the dough over the butter, enclosing it completely.
• Roll the dough with a rolling pin to seal the seams, making sure to lengthen the dough, rather than widening it.
• Transfer the dough to a baking sheet and cover with plastic wrap. Refrigerate for 1 hour.
• Roll out the dough on a floured surface until it's 8x24 inches (20x61 cm).
• Fold the top half down to the middle, and brush off any excess flour.
• Fold the bottom half over the top and turn the dough clockwise to the left. This completes the first turn.
• Cover and refrigerate for one hour.
• Roll out the dough again two more times, completing three turns in total and refrigerating for 1 hour in between each turn. If at anytime the dough or butter begins to soften, stop and transfer back to the fridge.
• After the final turn, cover the dough with plastic wrap and refrigerate overnight.
• To form the croissants, cut the dough in half. Place one half in the refrigerator.
• Flour the surface and roll out the dough into a long narrow strip, about 8x40 inches (20x101 cm).
• With a knife, trim the edges of the dough.
• Cut the dough into 4 rectangles.
• Place the chocolate on the edge of the dough and roll tightly enclosing it in the dough.
• Place the croissants on a baking sheet, seam side down.
• Repeat with the other half of the dough.
• Brush the croissants with the beaten egg. Save the rest of the egg wash in the fridge for later.
• Place the croissants in a warm place to rise for 1-2 hours.
• Preheat oven to 400°F (200°C).
• Once the croissants have proofed, brush them with one more layer of egg wash.
• Bake for 15 minutes or until golden brown and cooked through. Serve warm.
• Enjoy!

CHOCOLATE CROISSANTS

Steps:

• Preheat the oven to 425 degrees F. Unfurl the sheet of pastry and then cut it into 6 squares.
• Cut each square diagonally to give 2 triangles (they will appear quite small). Put the triangle with the wider part facing you and the point away from you.
• Break off small pieces of chocolate (approx.1cm/half inch) to place about 2cm/3/4-inch up from the wide end nearest you.
• Then carefully roll from that chocolate loaded end towards the point of the triangle.
• You should now have something resembling a straight croissant, seal it slightly with your fingertips and curl it around into a crescent.
• Place the chocolate croissants on a lined baking tray and paint with the beaten egg. Bake for 15 minutes until golden and puffy and exuberantly, if miniaturely, croissant-like.

CHOCOLATE CROISSANTS

Steps:

• For the croissant dough: In the bowl of your stand mixer, combine the flour, yeast, sugar and salt, then whisk together. Add 2 tablespoons of room temperature butter and beat with the paddle attachment. Mix on low speed until combined and the butter is no longer visible. Add the milk. Mix on low speed until the dough comes together, then switch to the dough hook. Knead on medium-high until the dough comes together into a smooth but still slightly loose ball, about 5 minutes. Remove from the mixer, then pat into a rectangle and wrap in plastic wrap. Let rest in the refrigerator for 1 hour.
• When the dough is almost done resting, make a rectangle of butter! Smush the remaining 2 1/2 sticks butter together into a rustic rectangle and dust all over with flour. Place it between two pieces of parchment paper (or butter wrappers) and press or roll it into a 6-by-8-inch rectangle. Roll the dough on a floured work surface to about 10 by 20 inches. Lay the butter rectangle in the center and fold one end over the butter. Fold the second end over the top, like folding a letter. This is the first turn. Wrap in plastic and chill 30 minutes.
• For the chocolate croissants: Unwrap the dough and set one straight edge closest to you. Roll to about 10 by 20 inches and fold the short ends in to meet in the center, then fold closed, like a book. (This is the second turn.) Wrap and chill 30 minutes, then complete another book turn. Wrap and chill for 30 minutes after the third turn. Complete one more book turn. Wrap and chill at least 2 hours or up to overnight.
• Beat the egg. Unwrap the dough and cut in half. Line 2 baking sheets with parchment paper. Working with half of the dough at a time, roll into a 10-by-14-inch rectangle and trim the edges with a pizza wheel to even it out. Cut into 6 rectangles by cutting it in half vertically, and then in thirds horizontally. Brush the rectangles with the egg wash. Lay a 1/2-ounce chocolate bar in the center of each rectangle, arranging it parallel to the short ends of the rectangle. Fold one end over the chocolate, and then the other end over that, again like a letter. Place seam-side down on one of the prepared baking sheets. Repeat with the remaining dough and chocolate. Spray a piece of plastic wrap with cooking spray and cover the croissants loosely. Let rise at room temperature until light, puffy and increased in size by about half, about 1 1/2 hours.
• Preheat the oven to 375 degrees F.
• Brush the croissants generously with the egg wash. Bake, rotating the baking sheets from top to bottom halfway through, until puffed and deep golden, 20 to 25 minutes. Let cool slightly on a rack.

CROISSANTS

Steps:

• Make the dough: Stir yeast, water, and 1 teaspoon sugar in a bowl. Let stand until foamy, about 5 minutes. Butter a large bowl; set aside. Put bread flour, all-purpose flour, remaining 3 tablespoons plus 2 teaspoons sugar, and the salt into the bowl of an electric mixer fitted with the dough hook; mix on low speed until combined. Add yeast mixture, milk, and butter; mix until dough just comes together.
• Knead dough: Scrape dough out onto a lightly floured work surface. Using lightly floured hands, knead until smooth, about 3 minutes. Transfer to buttered bowl, turning to coat.
• Let dough rise: Cover dough with plastic wrap; transfer to the refrigerator. Let rise until doubled in bulk, about 2 hours (dough should not spring back when you press it with your finger).
• Make the butter package: About 45 minutes after the dough begins rising, put flour and butter into the clean bowl of an electric mixer fitted with the paddle attachment. Mix on medium speed until well combined, 3 to 4 minutes. Scrape butter mixture out onto a piece of parchment paper; shape into a rectangle. Top with parchment, and roll out to an 8-by-10-inch rectangle. Transfer to a baking sheet, and refrigerate 30 minutes.
• Roll out dough: Turn out dough onto a lightly floured work surface; shape into a rectangle. Roll out to a 10 1/2-by-16-inch rectangle, about 1/2 inch thick, with short side facing you.
• Place butter package on dough: The butter package should be cool but pliable; your finger should leave an indentation but the butter should still hold its shape. If too soft, continue to refrigerate; if too firm, let stand at room temperature briefly. Place horizontally on bottom half of dough; remove parchment. Fold top half of dough over butter package, and pinch edges of dough to seal.
• Roll in butter: Turn dough so that a short side is facing you and the seam is on the right. Roll out to a 10-by-20-inch rectangle, about 1/2 inch thick (keep the corners as square as possible).
• Fold dough into thirds: Remove any excess flour with a pastry brush. Starting at the far end, fold rectangle in thirds as you would a business letter (this completes the first of 3 "turns").
• Mark dough: Mark the dough with your knuckle (later, this will help you remember how many turns have been completed). Wrap dough in plastic, and refrigerate 1 hour.
• Repeat process: Remove from refrigerator, and press the dough; it should be pliable but have some resistance. If too soft, return to refrigerator; if too firm, let stand at room temperature, 5 minutes. Repeat the preceding three steps to complete two more turns (make 2 marks for the second turn and 3 marks for the third turn); always start with a short side facing you and the seam on the right, rolling lengthwise before crosswise. After the second turn, wrap dough in plastic, and refrigerate 1 hour. After the third and final turn, wrap dough in plastic, and refrigerate 8 hours (or overnight).
• Roll out and chill dough: Turn out dough onto a lightly floured work surface, and roll out to a 30-by-16-inch rectangle. If dough becomes unmanageable, cut in half crosswise, and roll out two 15-by-16-inch rectangles (refrigerate 1 piece as you work with the other). Chill in freezer 15 minutes. Remove dough, and remeasure: It should match original dimensions; if not, roll out again. If dough becomes too warm or elastic, chill in freezer, 15 minutes.
• Cut dough: Cut dough into two 30-by-8-inch rectangles (or four 15-by-8-inch rectangles). Stack rectangles, lining up edges (if you have four smaller rectangles, make two stacks).
• Trim dough and cut into triangles: Using a pastry or pizza wheel and cutting at a 20-degree angle, trim a small wedge from one short side to create an angled side. Cut dough into triangles, each with a 4 1/2-inch base. You should have about 20 total.
• Cut slits: Cut a 1-inch slit in the middle of the base of each triangle. Separate the stacks, transferring half the triangles to a parchment-lined baking sheet; cover, and refrigerate.
• Begin shaping croissants: Working with one triangle at a time and keeping remaining triangles covered with a clean kitchen towel, hold the two corners of the base, and stretch to lengthen it slightly. Grasp inner corners formed by the slit in the base, and lift and stretch them toward the outer sides of the triangle; press to seal.
• Roll croissants: Using your fingertips, roll the base of the triangle up and away from you, stretching the dough slightly outward as you roll to elongate the point (when finished, the point should be tucked under the croissant).
• Finish shaping croissants: Bend the two ends toward you to form a crescent shape (the ends should almost touch). Transfer to parchment-lined baking sheets, spacing croissants 2 inches apart. Repeat with remaining triangles. Cover loosely with plastic wrap, and let stand in a warm place until croissants have doubled in bulk and are very soft, 1 1/2 hours to 2 1/4 hours, depending on the temperature of room.
• Brush with egg: Preheat oven to 400 degrees, with racks in upper and lower thirds. Brush tops of croissants with egg. Bake, rotating sheets halfway through, until croissants are puffed and golden brown, 20 to 25 minutes. Let cool slightly on sheets on wire racks. Serve warm or at room temperature.

CROISSANTS

Steps:

• Combine yeast, warm water, and 1 teaspoon sugar. Allow to stand until creamy and frothy.
• Measure flour into a mixing bowl. Dissolve 2 teaspoons sugar and salt in warm milk. Blend into flour along with yeast and oil. Mix well; knead until smooth. Cover, and let rise until over triple in volume, about 3 hours. Deflate gently, and let rise again until doubled, about another 3 hours. Deflate and chill 20 minutes.
• Massage butter until pliable, but not soft and oily. Pat dough into a 14x8-inch rectangle. Smear butter over top two thirds, leaving 1/4-inch margin all around. Fold unbuttered third over middle third, and buttered top third down over that. Turn 90 degrees, so that folds are to left and right. Roll out to a 14x6-inch rectangle. Fold in three again. Sprinkle lightly with flour, and put dough in a plastic bag. Refrigerate 2 hours. Unwrap, sprinkle with flour, and deflate gently. Roll to a 14x6-inch rectangle, and fold again. Turn 90 degrees, and repeat. Wrap, and chill 2 hours.
• To shape, roll dough out to a 20x5-inch rectangle. Cut in half crosswise, and chill half while shaping the other half. Roll out to a 15 x 5 inch rectangle. Cut into three 5 x 5 inch squares. Cut each square in half diagonally. Roll each triangle lightly to elongate the point, and make it 7 inches long. Grab the other 2 points, and stretch them out slightly as you roll it up. Place on a baking sheet, curving slightly. Let shaped croissants rise until puffy and light. In a small bowl, beat together egg and 1 tablespoon water. Glaze croissants with egg wash.
• Bake in a preheated 475 degrees F (245 degrees C) oven for 12 to 15 minutes.

CHOCOLATE CROISSANTS

Steps:

• Cut a slit into the side of each croissant; fill with about 2 tablespoons chocolate chips. In a shallow bowl, combine the sugar, cornstarch and cinnamon; whisk in milk until smooth. Whisk in the eggs, cream and vanilla. , Dip croissants into egg mixture. Place in two greased 15x10x1-in. baking pans. Bake at 400° for 7-9 minutes or until golden brown. Serve warm.

CHEF JOHN'S CHOCOLATE CROISSANTS

Steps:

• Place warm water in the bowl of a stand mixer. Sprinkle with yeast. Let yeast dissolve for 10 minutes. Add sugar and bread flour. Sprinkle with salt; add 3 tablespoons butter. Attach the bowl to the stand mixer. Mix dough with the dough hook just until butter is completely kneaded in and the dough forms a ball and pulls away cleanly from the sides of the bowl, 3 or 4 minutes.
• Transfer dough to a work surface and form into a semi-smooth ball. Place dough back in the mixer bowl; cover. Let rise in a warm spot until doubled, about 2 hours.
• Transfer dough to a lightly floured work surface. Push and press dough to deflate it, and form it into a rectangle. Fold into thirds by lifting one end over the middle third, and folding the other side onto the middle. Wrap in plastic wrap. Place on a rimmed baking sheet lined with a silicone mat. Refrigerate until chilled through, about 1 hour.
• Cut 1 stick of butter in 1/2 lengthwise and place halves slightly apart from each other on a length of parchment paper long enough to fold over the butter. Fold the parchment paper over the butter. Press butter down. Roll out with a rolling pin to a square about 8x8 inches. Refrigerate until a little chilled and just barely flexible, 10 or 15 minutes.
• Roll dough out into a rectangle slightly wider than the butter slab and just over twice as long. Place butter on one half of the dough leaving about 1 inch margin from the edge of the dough. Fold the other half of the dough over the butter. Dust work surface and dough with flour as needed.
• Press rolling pin down on dough to create ridges. Then roll out the ridges. Repeat this process. Keep pressing and rolling until dough is about the same size rectangle as you had before you folded it in half, dusting with just a bit of flour as necessary.
• Starting from the short side, fold one-third of dough over middle third. Then fold the other end over to form a small rectangle. Flatten out just slightly with rolling pin. Transfer to the silicone-lined baking sheet; cover with plastic wrap. Refrigerate until chilled, about 30 minutes.
• Transfer dough back to work surface and repeat pressing and rolling technique until dough is the size of the previous larger rectangle. Fold into thirds again, starting from the short side. Press and roll slightly. Transfer back to lined baking sheet. Cover and refrigerate about 15 minutes.
• Roll back out to a large rectangle. This time, fold dough in half. Then press and roll out into a 1/2-inch thick rectangle, using as little flour as needed to keep dough from sticking.
• Dust dough with flour and roll out to a rectangle about 1/8-inch thick. Cut dough lengthwise into 6 pieces using a pastry wheel.
• Pull and stretch out 1 of the dough pieces until ends are slightly tapered. Line 1 to 2 tablespoon of chocolate 1 inch parallel to the bottom edge and an equal amount of chocolate 1 more inch ahead. Roll dough up over the chocolate toward the top short edge to form a croissant with the seam at the bottom. Repeat with the remaining 5 dough pieces.
• Place shaped croissants on baking sheets lined with silicone mats. Whisk together egg and 1 tablespoon water to make the egg wash. Brush croissants with a large portion of the egg wash. Place in a warm area to allow them to rise, 60 to 90 minutes.
• Preheat oven to 400 degrees F (200 degrees C). Brush croissants gently but thoroughly again with egg wash. Sprinkle sea salt on top.
• Bake in preheated oven until beautifully browned, about 25 minutes. Transfer to a cooling rack. Cool to room temperature, about 1 hour.

CROISSANTS

Steps:

• Twenty-four hours before serving, start the détrempe: In the bowl of a stand mixer fitted with the dough hook, combine the flour, sugar, salt and yeast, and stir to combine. Create a well in the center, and pour in the water and milk. Mix on low speed until a tight, smooth dough comes together around the hook, about 5 minutes. Remove the hook and cover the bowl with a damp towel. Set aside for 10 minutes.
• Reattach the dough hook and turn the mixer on medium-low speed. Add the butter pieces all at once and continue to mix, scraping down the bowl and hook once or twice, until the dough has formed a very smooth, stretchy ball that is not the least bit sticky, 8 to 10 minutes.
• Form the dough into a ball and place seam-side down on a lightly floured work surface. Using a sharp knife, cut two deep perpendicular slashes in the dough, forming a "+." (This will help the dough expand into a square shape as it rises, making it easier to roll out later.) Place the dough slashed-side up inside the same mixing bowl, cover with plastic wrap and let rise at room temperature until about 1 1/2 times its original size, 45 minutes to 1 hour. Transfer the bowl to the refrigerator and chill for at least 4 hours and up to 12.
• As the dough chills, make the butter block: Place the sticks of butter side-by-side in the center of a large sheet of parchment paper, then loosely fold all four sides of the parchment over the butter to form a packet. Turn the packet over and use a rolling pin to lightly beat the cold butter into a flat scant 1/2-inch-thick layer, fusing the sticks and making it pliable. (Don't worry about the shape at this point.) The parchment may tear. Turn over the packet and unwrap, replacing the parchment with a new sheet if needed. Fold the parchment paper over the butter again, this time making neat, clean folds at right angles (like you're wrapping a present), forming an 8-inch square. Turn the packet over again and roll the pin across the packet, further flattening the butter into a thin layer that fills the entire packet while forcing out any air pockets. The goal is a level and straight-edged square of butter. Transfer the butter block to the refrigerator.
• Eighteen hours before serving, remove the dough from the refrigerator, uncover and transfer to a clean work surface. (It will have doubled in size.) Deflate the dough with the heel of your hand. Using the four points that formed where you slashed the dough, stretch the dough outward and flatten into a rough square measuring no more than 8 inches on one side.
• Place 2 pieces of plastic wrap on the work surface perpendicular to each other, and place the dough on top. Wrap the dough rectangle, maintaining the squared-off edges, then roll your pin over top as you did for the butter, forcing the dough to fill in the plastic and form an 8-inch square with straight sides and right angles. Freeze for 20 minutes.
• Remove the butter from the refrigerator and the dough from the freezer. Set aside the butter. Unwrap the dough (save the plastic, as you'll use it again) and place on a lightly floured surface. Roll the dough, dusting with flour if necessary, until 16 inches long, maintaining a width of 8 inches (barely wider than the butter block). With a pastry brush, brush off any flour from the surface of the dough and make sure none sticks to the surface.
• You're going to enclose the butter block in the dough and roll them out together. To ensure they do so evenly, they should have the same firmness, with the dough being slightly colder than the butter. The butter should be chilled but able to bend without breaking. If it feels stiff or brittle, let sit at room temperature for a few minutes. Unwrap the butter just so the top is exposed, then use the parchment paper to carefully invert the block in the center of the dough rectangle, ensuring all sides are parallel. Press the butter gently into the dough and peel off the parchment paper. You should have a block of butter with overhanging dough on two opposite sides and a thin border of dough along the other two.
• Grasp the overhanging dough on one side and bring it over the butter toward the center, then repeat with the other side of the dough, enclosing the butter. You don't need the dough to overlap, but you want the two sides to meet, so stretch it if necessary, and pinch the dough together along all seams so no butter peeks out anywhere. Lift the whole block and dust a bit of flour underneath, then rotate the dough 90 degrees, so the center seam is oriented vertically.
• Orient the rolling pin perpendicular to the seam and lightly beat the dough all along the surface to lengthen and flatten. Roll out the dough lengthwise along the seam into a 24-inch-long, 1/4-inch-thick narrow slab, lightly dusting underneath and over top with more flour as needed to prevent sticking. Rather than applying pressure downward, try to push the dough toward and away from you with the pin, which will help maintain even layers of dough and butter. Remember to periodically lift the dough and make sure it's not sticking to the surface, and try your best to maintain straight, parallel sides. (It's OK if the shorter sides round a bit - you're going to trim them.)
• Use a wheel cutter or long, sharp knife to trim the shorter ends, removing excess dough where the butter doesn't fully extend and squaring off the corners for a very straight-edged, even rectangle of dough. Maintaining the rectangular shape, especially at this stage, will lead to the most consistent and even lamination. If at any point in the process you see air bubbles in the dough while rolling, pierce them with a cake tester or the tip of a paring knife to deflate and proceed.
• Dust any flour off the dough's surface. Grasp the short side of the rectangle farther from you and fold it toward the midline of the dough slab, aligning the sides. Press gently so the dough adheres to itself. Repeat with the other side of the dough, leaving an 1/8-inch gap where the ends meet in the middle. Now, fold the entire slab in half crosswise along the gap in the center. You should now have a rectangular packet of dough, called a "book," that's four layers thick. This is a "double turn," and it has now quadrupled the number of layers of butter inside the dough.
• Wrap the book tightly in the reserved plastic. If it is thicker than about 1 1/2 inches, or if it's lost some of its rectangularity, roll over the plastic-wrapped dough to flatten it and reshape it. Freeze the book for 15 minutes, then refrigerate for 1 hour.
• Let the dough sit at room temperature for about 5 minutes. Unwrap and place on a lightly floured surface. Beat the dough and roll out as before (Step 10) into another long, narrow 3/8-inch-thick slab. It should be nice and relaxed, and extend easily. Dust off any excess flour.
• Fold the dough in thirds like a letter, bringing the top third of the slab down and over the center third, then the bottom third up and over. This is a "simple turn," tripling the layers. Press gently so the layers adhere. Wrap tightly in plastic again and freeze for 15 minutes, then refrigerate for 1 hour.
• Let the dough sit at room temperature for about 5 minutes, then unwrap and place on a lightly floured surface. Beat the dough and roll out as before, but into a 14-by-17-inch slab (15-by-16-inch for pain au chocolat or ham and cheese croissants). The dough will start to spring back, but try to get it as close to those dimensions as possible. Brush off any excess flour, wrap tightly in plastic, and slide onto a baking sheet or cutting board. Freeze for 20 minutes, then chill overnight (8 to 12 hours). If making pain au chocolat or ham and cheese croissants, see recipes.
• Four and a half hours before serving, arrange racks in the upper and lower thirds of the oven. Bring a skillet of water to a simmer over medium-high heat. Transfer the skillet to the floor of the oven and close the door. (The steam released inside the oven will create an ideal proofing environment.)
• As the steam releases in the oven, line two rimmed baking sheets with parchment paper and set aside. Let the dough sit at room temperature for about 5 minutes. Unwrap (save the plastic for proofing), place on a very lightly floured surface, and, if necessary, roll out to 17-by-14 inches. Very thoroughly dust off any excess flour with a pastry brush. Use a wheel cutter or long knife and ruler to cut the shorter sides, trimming any irregular edges where not all the layers of dough fully extend and creating a rectangle that's exactly 16 inches long, then cut into four 4-by-14-inch rectangles.
• Separate the rectangles, then use the ruler and wheel cutter to slice a straight line from opposite corners of one rectangle to form two long, equal triangles. Repeat with the remaining rectangles to make 8 triangles. Trim the short side of each triangle at a slight angle, making them into triangles with longer sides of equal length.
• Working one triangle at a time, grasp the two corners of the shorter end, the base of the crescent, and tug gently outward to extend the points and widen the base to about 3 inches. Then, gently tug outward from about halfway down the triangle all the way to the point, to both lengthen the triangle and thin the dough as it narrows. Starting at the base (the short end), snugly roll up the dough, keeping the point centered and applying light pressure. Try not to roll tightly or stretch the dough around itself. Place the crescent on one of the parchment-lined baking sheets, resting it on the point of the triangle. If the dough gets too soft while you're working, cover the triangles and freeze for a few minutes before resuming rolling. Space them evenly on the baking sheets, four per sheet. Very loosely cover the baking sheets with plastic wrap, so the croissants have some room to expand.
• Three and a half hours before serving, open the oven and stick your hand inside: It should be humid but not hot, as the water in the skillet will have cooled. You want the croissants to proof at 70 to 75 degrees. (Any hotter and the butter will start to melt, leading to a denser croissant.) Place the baking sheets inside the oven and let the croissants proof until they're about doubled in size, extremely puffy, and jiggle delicately when the baking sheet is gently shaken, 2 to 2 1/2 hours. Resist the urge to touch or poke the croissants as they proof: They're very delicate. Try not to rush this process, either, as an underproofed croissant will not be as light and ethereal.
• Remove the baking sheets from the oven and carefully uncover them, then transfer to the refrigerator and chill for 20 minutes while you heat the oven. Remove the skillet from the oven and heat to 375 degrees.
• In a small bowl, stir the yolk and heavy cream until streak-free. Using a pastry brush, gently brush the smooth surfaces of each crescent with the yolk and cream mixture, doing your best to avoid the cut sides with exposed layers of dough.
• Transfer the sheets to the oven and bake for 20 minutes. Rotate the baking sheets and switch racks, and continue to bake until the croissants are deeply browned, another 10 to 15 minutes. Remove from the oven and let cool completely on the baking sheets.

CROISSANTS

Steps:

• Put the flour, salt and sugar in a mixing bowl. Measure 300ml cold water into a jug, add the yeast and stir. Make a well in the flour and pour in the liquid. Mix, then knead on your work surface for 10 mins. Shape into a ball, put in a lightly oiled bowl, cover and chill for at least 2 hrs.
• Put the butter between 2 sheets of baking parchment. Using a rolling pin, bash and roll it into a rectangle about 20 x 15cm. Leave wrapped in the baking parchment and chill.
• Transfer the chilled dough to a floured surface and roll into a 40 x 20cm rectangle. Place the unwrapped slab of butter in the centre of the dough, so that it covers the middle third.
• Fold one side of the dough up and halfway over the butter.
• Fold the other side of the dough up and over the butter in the same way, so that the two edges of the dough meet in the centre of the butter.
• Fold the dough in half so that the point where the ends of the dough meet becomes the seam. Wrap in cling film and chill for 30 mins.
• Repeat the rolling, folding and chilling process (steps 3-6) twice more in exactly the same way - rolling the pastry while it's still folded - without adding more butter. Wrap and chill overnight.
• The next day, roll the dough out on a floured surface into a large rectangle, measuring about 60 x 30cm. Using a sharp knife or pizza cutter, trim the edges to neaten.
• Cut the dough in half lengthways so that you have 2 long strips, then cut each strip into 6 or 7 triangles with 2 equal sides.
• Take each triangle in turn and pull the two corners at the base to stretch and widen it.
• Starting at the base of each triangle, begin to gently roll into a croissant, being careful not to crush the dough.
• Continue rolling, making sure the tip of each triangle ends up tucked under the croissant to hold in place. If adding any fillings (see tips, below), place across the widest part of the triangle before rolling up.
• Bend the ends of the croissants inwards, then transfer to baking trays lined with baking parchment, spaced well apart. Cover with lightly oiled cling film and leave to rise for 2 hrs, or until doubled in size.
• Heat oven to 200C/180C fan/gas 6. Mix the beaten egg with a pinch of salt and use to generously glaze the croissants. Bake for 15-18 mins until risen and golden brown, then cool on wire racks.
