Mustard Batons Recipes

MUSTARD BATONS

Steps:

• Heat oven to 400 degrees. Line two baking sheets with parchment paper or baking mats.
• On a lightly floured surface, roll out one sheet of pastry into a rectangle, about 12 by 16 inches. Turn so that a short side is facing you. Spread half of the mustard over the lower half of the rectangle, leaving a 1/8-inch margin around the edges. Fold the top half over the lower half. Using the tip of a sharp knife and a straight edge (such as a clean ruler), cut it into 1-inch-wide strips from top to bottom. Transfer to prepared baking sheets, leaving a bit of space between batons, and refrigerate until ready to bake. Repeat with remaining pastry and mustard.
• Beat the egg with a splash of cold water, and brush mixture lightly onto batons. Sprinkle with poppy or sesame seeds, if using. Bake about 15 minutes, rotating pans after 8 minutes, until puffed and golden brown. Let rest a few minutes before serving.

MUSTARD MASHED POTATOES

Steps:

• Place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 20 minutes. Drain and allow to steam dry for a minute or two. Mash potatoes in a large bowl with the butter and milk, and season with salt and pepper.
• Whip the potatoes using an electric mixer set on medium until smooth, 3 to 4 minutes, adding more milk if the potatoes are too dry. Beat in the whole grain mustard, and serve immediately.

HOMEMADE MUSTARDS

Steps:

• In a nonreactive container, combine mustard seeds with alcohol (beer, wine, or sherry; according to recipe) and vinegar. Let sit 48 hours. Check periodically to make sure seeds are covered by liquid; add more if necessary.
• Transfer seeds and liquid to a food processor. Add remaining ingredients. Process until seeds become creamy, 4 to 6 minutes. Store in an airtight container in the refrigerator for at least 1 week before using to let the flavors develop. The mustard will keep for up to 1 month.

MUSTARD AND GRUYERE BATONS

Steps:

• Unfold the sheet of puff pastry on a well-floured board, and roll it to an 11-by-13-inch rectangle with a floured rolling pin. (Diagonal strokes keep the pastry rectangular.) With a shorter end closest to you, brush the lower half of the pastry evenly with the mustard, leaving a 1/2-inch border around the edges. Brush the border of the pastry with the egg wash and fold the top half over the bottom half, lining up the edges. Place the pastry on a sheet pan lined with parchment paper and chill for 15 minutes.
• Place the pastry on a board and trim the three irregular edges with a sharp knife. With the folded edge away from you, cut the pastry in 1-by-6-inch strips. You will have 10 to 12 batons. Spread the batons out on the sheet pan so they're not touching. Brush the tops lightly with the egg wash (don't allow the egg wash to drip down the sides) and sprinkle evenly with the Gruyere, Parmesan, and 1 1/2 teaspoons sea salt. Chill for at least 15 minutes.
• When ready to bake, preheat the oven to 400 degrees F.
• Bake the batons for 15 to 18 minutes, until golden brown and puffed. Allow to cool on the pan for 3 minutes and serve warm.
