Mille Foglie Recipes

Steps:

• Preheat oven to 400 degrees F (200 degrees C). Line a baking sheet with a silicone sheet.
• Separate dough at the seams into 4 squares and place on prepared baking sheet. Score the dough all over with the tines of a fork to prevent it from rising too much when baking. Lightly sprinkle dough sheets with white granulated sugar.
• Cover with a sheet of parchment paper and 3 sheets of aluminum foil. Nest another baking sheet on top to apply some pressure to the dough while it bakes.
• Bake in preheated oven 15 minutes; remove top pan and foil and gently peel off the parchment paper. Return pan to oven and bake until pastry is beautifully browned, 10 to 15 minutes. (Optionally, you can bake about 7 minutes after uncovering, then flip sheets over and bake until brown on the other side, another 7 minutes.)
• Transfer to cooling rack and cool completely before cutting.
• Square the sheets by trimming uneven edges off sheets using a sharp serrated knife with light sawing motion to keep the pastry from breaking. Cut each rectangle crosswise into 3 equal smaller rectangles. Use 3 small rectangles per pastry.

Steps:

• Make custard:
• Bring 2 cups milk with salt to a boil in a 3-quart heavy saucepan. Meanwhile, whisk together yolks, sugar, flour, cornstarch, and remaining 1/4 cup milk in a bowl. Add one third of hot milk to yolk mixture in a slow stream, whisking, then add to milk remaining in saucepan, whisking.
• Bring custard to a boil over moderate heat, whisking, and boil, whisking, 2 minutes. Remove from heat and stir in butter until melted, then stir in grappa. Transfer custard to a bowl and chill, its surface covered with wax paper, until cold, at least 1 hour.
• Cook rhubarb while custard chills:
• Simmer rhubarb, water, sugar, and grappa in cleaned 3-quart heavy saucepan, uncovered, stirring gently once or twice, until rhubarb is tender but not falling apart, about 4 minutes. Set pan in a bowl of ice and cold water and let stand 2 minutes to stop cooking.
• Slowly pour rhubarb mixture into a sieve set over a bowl. Return syrup to saucepan, reserving rhubarb, and boil until reduced to about 1/2 cup, about 10 minutes. Keep rhubarb and syrup, covered, at room temperature until ready to use.
• Prepare pastry while rhubarb cooks:
• Preheat oven to 400°F.
• Unfold 1 puff pastry sheet and gently roll out into a 14-inch square with a rolling pin on a lightly floured surface. Transfer to a buttered large baking sheet and prick all over with a fork. Repeat with remaining sheet.
• Bake in upper and lower thirds of oven, switching position of sheets halfway through baking, until pastry is puffed and golden, about 15 minutes total. Cool on baking sheets on racks.
• Trim edges of pastry with a large serrated knife. Cut each sheet into 12 (3-inch) squares and break pastry scraps into small shards.
• Assemble millefoglie:
• Beat cream (for custard) in a bowl with an electric mixer until it just holds soft peaks. Whisk custard to loosen, then fold in whipped cream gently but thoroughly.
• Dollop 2 rounded tablespoons of grappa cream on each of 8 dessert plates and top with half of rhubarb. Cover cream and rhubarb on each plate with a pastry square. Make another layer with remaining grappa cream, rhubarb, and pastry squares, then top with pastry shards. Sift confectioners sugar evenly over each serving and drizzle with syrup.
