Double-Almond Pie Crust
- 3 1/2 tablespoons egg yolks (from 3 to 4 eggs), whisked
- 3/4 cup unsalted butter, very cold
- 1 1/2 cups all-purpose flour
- 3/8 cup almond flour
- 3/4 cup powdered sugar
- 1 teaspoon salt
- 1/2 teaspoon baking powder
- 3/4 teaspoon almond extract
- Baking beads or dry beans, as needed
Fill a large stock pot with hot water, then set over low heat and bring to 153 F. Clip a digital thermometer to the rim of the pot, with the tip well submerged, to monitor the temperature.
When the water reaches 153 F, place the egg yolks in a zip-close plastic bag. Slowly lower the open bag into the heated water until the top is nearly at the surface of the water, then seal it. The goal is to use the water pressure to squeeze as much air as possible out of the bag. Once sealed, the bag should sink.
Submerge the bag of yolks, and let them cook in the 153 F water for 45 minutes. Keep an eye on the thermometer and adjust the heat as needed to keep the temperature at or near 153 F.
While the yolks cook, dice the chilled butter and combine it in a food processor with both flours, the powdered sugar, salt and baking powder. Pulse until the mixture takes on the texture of cornmeal.
Add the almond extract and cooked egg yolks gradually, while continuing to pulse the food processor. Continue processing until the dough starts to bind. Although it may look quite dry, it will cohere eventually.
Shape the dough into a ball, flatten it into a thick disk, then wrap it tightly in plastic wrap. Put the wrapped dough in the refrigerator and let it rest for an hour. As it rests, the butter in the dough will harden and the gluten will grow more elastic. While the dough rests, you can make the pastry cream and caramelized almonds from the recipes included here.
When the dough is nearly finished chilling, heat the oven to 375 F.
Unwrap the dough and roll it into a circle about 1/8 inch thick and about 14 inches around (or 2 inches larger in diameter than your pie pan). If you find that the dough is too sticky to roll, either chill it again or place it between 2 pieces of plastic wrap or kitchen parchment, then roll it.
Line a 12-inch pie pan with the dough; do not trim off the excess. Instead, let the edges drape over the sides of the pan. Press the dough firmly into the pan interior. If you don't need to use the crust right away, cover the unbaked crust in plastic wrap and store it in the refrigerator. For longer-term storage, vacuum seal it and stick it in the freezer.
To prepare the crust for baking, prick it with a fork all over, then press kitchen parchment over the top to protect it during baking. Fill the pan with baking beads or dry beans, and press them against the walls so that the dough doesn't droop while it is in the oven.
Place the pie pan on a baking sheet, and bake until it turns golden brown, about 12 minutes. Midway through the baking, rotate the pie pan a half turn so that it browns evenly.
Carefully remove the beans and parchment. If the crust still looks a little wet, return it to the oven for another 2 to 3 minutes.
Cool the crust to room temperature, then use a knife to trim any excess crust from the edges of the pan.
