Tarte Flambé

Line a rimmed baking sheet with parchment paper.

Cut the puff into a rectangle, making sure all sides are trimmed, and place on prepared pan. Score a ½” border on each side. Dock the center by poking holes all through the center rectangle within the scored border. Refrigerate until ready to assemble.

In a large sauté pan, cook the bacon over medium heat. Cook just until some of the fat is released, 3 to 5 minutes. The bacon will finish cooking in the oven. Remove the bacon from the pan and immediately add the onions. Cook the onions in the bacon fat until softened, 2 to 3 minutes. Season with salt and pepper. Remove from heat and combine with bacon.

To assemble: spread crème fraîche evenly over dough. Sprinkle an even layer of the onion/bacon mixture over the crème fraîche. Grate nutmeg evenly over the top. Chill the tart for 30 minutes.

Preheat oven to 375°F convection (400°F conventional).

Bake until dough is puffed and looks dry, about 10 minutes. Reduce the temperature to 325°F convection (350°F conventional). Bake until crust is a deep golden brown and the bottom is evenly browned, 25 to 30 minutes. Let cool slightly before cutting and serving. Best served warm.

Cut butter into pieces approximately 1” squares. Combine with flour and salt in the bowl of a stand mixer fitted with the paddle attachment.

Start the mixer and immediately start streaming in water. When the flour has absorbed the water and no more dry spots remain, stop mixing. You should still be able to see large chunks of butter. Roughly press out into a rectangle. Cover and refrigerate the dough for 20 minutes.

After the dough has rested, roll it out into a ¼” thick rectangle. Fold the dough like a business letter. You have completed one single turn. Rotate the dough 90 degrees and repeat the process. Cover and refrigerate for at least 1 hour.

Repeat the rolling and folding method 2 more times. The dough should have received 4 single turns. Wrap the dough and chill again for 1 hour. The dough is now ready to be rolled out and used as desired.
