Hazelnut Tart Shell

Directions

1. 1
   Grind the hazelnuts and prepare the dry ingredients.
2. 2
   In a food processor, combine the hazelnuts and 1 1/2 cup of the flour and grind to a fine powder.
3. 3
   In a small bowl, whisk together the hazelnut mixture, the rest of the flour, the baking powder, and the salt.
4. 4
   Cream the butter and incorporate the eggs (see the Notes on creaming butter and room-temperature eggs):
5. 5
   Place the butter in the bowl of the stand mixer with the paddle attachment and beat on medium speed for 1 minute.
6. 6
   Add the sugar and beat on medium-high speed until the mixture becomes fluffy and almost white in color, approximately 6 to 8 minutes, stopping the mixer occasionally to scrape down the sides of the bowl.
7. 7
   Add the egg yolks, one at a time, and continue to beat until they are fully incorporated and the batter looks smooth and glossy, 1 to 2 minutes.
8. 8
   Add the dry ingredients and finish the dough:
9. 9
   Add the dry mixture, all at once, to the butter mixture.
10. 10
    Use a rubber spatula and fold the dry mixture into the butter mixture with a few turns before turning on the mixer.
11. 11
    Mix the dough at slow speed until thoroughly combined, 1 to 2 minutes.
12. 12
    Stop the mixer, scrape down the sides of the bowl with a rubber spatula, and mix on slow speed for another 30 seconds.
13. 13
    Separate the dough into two mounds.
14. 14
    Wrap each mound in plastic wrap and press down to form two 1-inch-thick disks.
15. 15
    Transfer the dough to the refrigerator and chill for 2 hours or overnight.
16. 16
    Roll and blind-bake the tart dough.
17. 17
    Follow the technique for rolling tart dough.
18. 18
    On a cool, dry counter surface, roll the dough into a 1/8-inch-thick circle.
19. 19
    Line the tart pan with the dough and freeze the tart shell for 1/2 hour.
20. 20
    Preheat the oven to 350F.
21. 21
    Remove the shell from the freezer, line it with parchment paper, aluminum foil, or a large coffee filter, and fill it with pie weights or dried beans.
22. 22
    Transfer the shell to the oven and bake for 30 minutes.
23. 23
    Remove from the oven and let it sit for 10 minutes; take out the liner and weights and place the shell back in the oven.
24. 24
    (You can save the beans to use as pie weights again.)
25. 25
    Bake until it is golden brown, 10 to 15 minutes.
