Pistachio Linzer Thumbprints

• 2 cups roasted unsalted pistachios (10 ounces)
• 2 cups all-purpose flour
• 1/2 cup plus 1 tablespoon sugar
• 1 teaspoon baking powder
• 1 teaspoon cinnamon
• 1/4 teaspoon salt
• 2 sticks (1/2 pound) cold unsalted butter, cut into 1/2-inch cubes
• 2 large eggs, separated
• 1 teaspoon pure vanilla extract
• 1 tablespoon finely grated lemon zest
• 2/3 cup seedless raspberry jam
• Confectioners' sugar, for dusting

1. In a food processor, grind 1 cup of the pistachios until coarsely chopped; transfer to a plate.
2. Add the remaining 1 cup of pistachios to the processor along with 1/2 cup of the flour and pulse until the nuts are finely ground.
3. Add the remaining 11/2 cups flour along with the sugar, baking powder, cinnamon and salt and pulse until combined.
4. Add the butter and pulse until the mixture resembles a coarse meal.
5. Add the egg yolks, vanilla and lemon zest and pulse until the dough begins to come together.
6. Transfer the dough to a bowl and refrigerate until firm.
7. Preheat the oven to 350.
8. Line 2 baking sheets with parchment or wax paper.
9. In a medium bowl, beat the egg whites until frothy.
10. Roll scant tablespoons of the dough into 1-inch balls.
11. Dip the balls in the beaten whites, then roll them in the chopped pistachios.
12. Arrange the cookies 2 inches apart on the prepared baking sheets.
13. With a floured finger, make an indentation in the center of each.
14. Chill the cookies until firm.
15. Using a small spoon or a pastry bag fitted with a 1/4-inch tip, fill each cookie with 1/2 teaspoon of the jam.
16. Bake the cookies in the lower half of the oven for about 25 minutes or until golden; shift the pans halfway through baking.
17. Cool the cookies on the baking sheets.
18. Sift confectioners' sugar over the cookies.
19. Using a moistened finger or soft brush, tap the center of each cookie so that the jam shines through the sugar.
