½ lb (2 sticks) unsalted butter, slightly softened
2 t vanilla
1 large egg yolk (Medrich lists as optional, but this is the holidays, c'mon... So I added it)
½ cup (1.5 oz) powdered sugar, or more, to taste
Instructions
Either line your cookie sheets with parchment paper or leave them ungreased. Set aside.
Fit your food processor with the mincing blade. Pule the nuts until half of them look pulverized and the rest look chopped. Move the nuts to a bowl and wipe out the food processor to remove the excess oil from the nuts.
Put the granulated sugar into the processor and process until it is fine and powdery. Add the flour and salt and process to mix. Add the butter, vanilla and egg yolk. Process until the mixture looks damp and begins to clump. Add the nuts and pulse until combined. Place the dough in a bowl with a lid and cover the dough with wax paper, pressing it into he dough. Put the lid on the bowl and chill for 2 hours or, even better, overnight (I did overnight).
The next day or when you are ready to bake, preheat the oven to 325 F. If you will be baking 2 sheets at a time, place the racks in the upper and lower thirds of the oven.
Shape slightly heaping tablespoon balls of dough into balls (Medrich says you can also do crescents). Place the cookies 2 inches apart--do not do more than 12 cookies per sheet, I tried the first time and the cookies definitely spread more. Bake the cookies for 22-24 minutes, or until "lightly colored on top and golden brown on the bottom." Rotate your pans top to bottom and front to back halfway through to ensure even baking.
Let the cookies cool on the pans for 5 minutes. Then sieve powdered sugar over the tops of them and let finish cooling. When the cookies had mostly cooled, I also gently shook them in a bag full of powdered sugar (requiring more than the half cup) because I like a wedding cookie that is coated in powdered sugar more thoroughly. Cool cookies totally before storing.
These cookies store well except for the fact that the powdered sugar will absorb moisture. Sieve additional powdered sugar over them before serving if that happens.
