ALSATIAN ONION TART

Steps:

• Heat the oil and butter in a cast-iron or other heavy-based 10- to 12-inch skillet. Add the onions and sugar, season with salt and pepper, and sauté over medium-high heat, stirring frequently, until lightly browned. Lower the heat and continue to cook the onions until very soft and evenly browned, stirring frequently, another 30 to 40 minutes; you may need to add a little more oil. When the onions are done, transfer them to a strainer and drain.
• Heat the oven to 375°F. If using a tart pan with a removable bottom, put it on a baking sheet. In a bowl, whisk the eggs and cream. Season with 3/4 tsp. salt, a scant 1/2 tsp. pepper, and the nutmeg. Add the drained onions and half of the cheese and blend thoroughly. Fill the prepared tart shell with the onions and custard. Top with the remaining cheese and bake until the tip of a knife comes out clean and the top of the tart is puffed and brown, 40 to 45 minutes. Let cool for at least 15 to 20 minutes before serving.

FRENCH ONION TART

Steps:

• Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
• On a work surface, roll the puff pastry into a roughly 10 by 16-inch rectangle. With a sharp knife, trim uneven edges to make a perfect rectangle. Evenly cut off the outer 1 inch of each side of the rectangle in strips; put the puff sheet on the baking sheet. Dip your finger in water and run around the top edges of the rectangle and replace the removed strips of pastry along the edges of the sheet, pressing lightly to adhere. With a fork, pierce the interior of the tart shell to prevent rising; do not pierce the adhered edges. Bake until the outer edges have puffed and are golden in color; about 15 minutes. Set aside.
• Heat 2 tablespoons olive oil in a large skillet over medium-low heat. Add onions and thyme sprigs and season well with salt and pepper, to taste. Cook, stirring occasionally, until the onions begin to brown. Add the stock, a tablespoon at a time, as the pan gets dry, scraping and stirring the brown bits that are stuck to the bottom oft the pan. When the onions are caramelized to a dark golden color, remove from the heat and discard the leafless thyme sprigs (the leaves fall off while cooking).
• When ready to serve, preheat the oven to 350 degrees F. Evenly spread the caramelized onions on the cooked pastry shell and heat in the oven until warmed through, 5 to 7 minutes. Remove from oven, to a cutting board and cut into wedges. Arrange on a serving platter and garnish each wedge with a sprig of fresh thyme. Serve immediately and enjoy!

• Heat the oil in a 12-inch skillet over medium heat. Add the onion and cook for about 15 minutes or until golden, stirring often. Season to taste and let cool.
• Unfold the pastry sheet on a lightly floured surface. Roll into a 12-inch square. Place on the prepared baking sheet. Brush the edges of the square with water. Fold over the edges 1/2 inch on all sides, pressing firmly with a fork to form a rim. Prick the pastry thoroughly with a fork.
• Spread the onion mixture over the pastry crust. Top with the gruyere and parmesan cheeses and sprinkle with the chives.
• Bake for 20 minutes or until golden and bubbly. Cool for 5 minutes on a wire rack. Cut into approximately 3 x 2-inch rectangles. Serve warm.

DEBORAH MADISON'S FRAGRANT ONION TART

Steps:

• To make the filling, cut onions in half, peel them, and if they are strong, put them in a bowl of cold water. It doesn't take long for that to reduce their sting. Finely dice them.
• If you're using bacon, fry until browned and nearly crisp, then scoop out and drain on a paper towel. Throw out bacon grease, wipe out pan and add 2 tablespoons butter. When melted, add onions, thyme and 3/4 teaspoon salt. Cook over medium heat, stirring occasionally, about 25 minutes. The onions needn't be caramelized, but should just take on a faint golden hue. When done, let them cool slightly. Taste for salt (they'll be very sweet, you might want to add more) and season well with pepper.
• While onions cook, whisk eggs with crème fraîche and milk. Stir in cooled onions, cheese and bacon, if using.
• To make the crust, put flour and 1/4 teaspoon salt in the bowl of a stand mixer fitted with a paddle attachment. Add 6 tablespoons butter and turn mixer to low speed until butter has broken into small, pebble-size pieces. Drizzle in ice water until dough looks clumpy and damp. (You'll use about 3 tablespoons, fewer if butter was soft.) Form dough into a disk or a rectangle to correspond to the shape pan you're using. You have a few choices: a 9-inch tart pan, a square tart pan or a rectangular one (11 by 81/2 inches), all with removable bottoms. Wrap dough in plastic and refrigerate.
• Heat oven to 400 degrees. Roll dough to fit tart pan, then drape dough in pan. Neatly press dough into pan and shape it. Set it on a sheet pan. Pour onion mixture into tart pan, and bake until surface is golden and browned in places, 45 to 50 minutes. Let cool to warm before cutting into slices and serving.

ONION TART

Steps:

• Sift the flours, salt; mustard powder and cayenne into a bowl, and then rub in the margarine until you get a crumbly mixture.
• Stir in the cheese and add enough cold water to make dough that leaves the bowl clean.
• Wrap the dough in plastic and put in the fridge for 30 minutes.
• Melt the butter in a heavy based frying pan, add the onions, get them coated in the butter, cook them uncovered on a medium heat for approx 30 minutes, they have to be reduced and turned a deep brown.
• Stir from time to time, if they are still pale at the end of the cooking time, turn up the heat and cook for another 10 minutes until they have the right color.
• Preheat oven to 350F and put a baking sheet in the oven.
• Grease an 8 inch fluted flan tin, roll out the pastry and line the tin, prick the base with a fork, place the tin on the baking sheet in the oven and bake for 15 minutes.
• Remove from the oven and brush with some beaten egg (from the filling) return to the oven for 5 minutes.
• Then spread the onions all over the base of the flan, mix the eggs with the milk, salt and pepper, and pour as much as possible over the onions, you might have some left it depends on how much the onions have reduced.
• Sprinkle the cheese over the top and bake for 30 minutes (on the baking sheet again) or until the filling is golden brown and puffy.

ONION TART

Steps:

• Blend flour and salt in the bowl of a food processor. Scatter butter over flour, top with lid and pulse 12 pulses to cut butter into flour to a coarse meal consistency.
• Dump butter-flour mixture into a medium stainless bowl. Make a well in the center and pour ice-cold water into the well.
• Using a flexible plastic dough scraper instead of your warm hands, bring the dough together by folding and pressing. Be firm and brisk and get the dough past its shaggy stage into a neat disk, trying to avoid using your hands or too much kneading. Refrigerate the dough for 30 minutes. Heat the oven to 375 degrees.
• Meanwhile, cut the onions in half and peel them. Slice the halves with the ribs (root end to sprout end direction), not against, to create julienne slices rather than half moons.
• In a wide sauté pan over medium-low heat, melt the bacon fat and slowly sweat the onions until they are caramelized. Take all the minutes you need - 25 or so - to let them soften to translucent, then to let the water they release start to evaporate, then to allow the sugars they contain to start to brown in the pan, so that you end up with soft, sweet and evenly browned onions. This is achieved by a slow caramelization. Set onions aside to cool.
• Roll tart dough out to a 1/4-inch-thick round, and drape over a round 10-inch fluted false-bottom tart pan. Lay dough into the pan, gently pressing into the bottom, and roll the pin across the pan to cut off the excess dough. Use your fingers to press the edges into the flutes, accentuating the shape of the dough edge. Dock the bottom of the dough with the tines of a fork, weight the pastry with beans or weight and blind-bake for 25 minutes.
• In a bowl, beat the egg with the cream. Stir in the caramelized onions. Season with pepper, nutmeg and salt to taste. Stir well, and make sure the onions are all evenly coated with the custard.
• Remove tart shell from oven, and slip it onto a baking sheet. Remove weights, fill with the onion-custard mixture and distribute it evenly. Return tart to oven on the sheet, and bake for 25 minutes, or until custard has set, the tops of the onions start to achieve a deeper brown and the dough is dark golden brown at the edges.
• Remove from the ring, and allow to cool just a few minutes on the rack, so that the piping hot tart shell can kind of tighten up enough to be sliced with a sharp chef's knife. (In the first few minutes straight out of the oven, the dough is kind of soft from the heat, possibly giving you the false impression that you have a soggy tart. Let it sit on the rack just to shake off this initial soft stage and to recrisp and refirm, which it will.) Cut into wedges, and serve while hot.
