Makes about 3 dozen cookies
Ingredients
- 2 1/2 cups sliced blanched almonds
 - 1/4 teaspoon salt
 - 1/3 cup plus 1 tablespoon confectioners’ sugar
 - 3/4 teaspoon almond extract
 - 1 1/3 cups granulated sugar
 - 1/2 cup egg whites
 - 1 tablespoon grated lemon zest
 - Coarsely chopped blanched almonds and confectioners’ sugar, as needed, for garnish
 
Directions
- Line two baking sheets with parchment paper.
 - In a food processor fitted with the steel blade, process the sliced almonds, sugars, lemon zest, salt, and extract until they form a coarse paste, 1 to 2 minutes.
 - Slowly add the egg whites and continue to process until the mixture forms a smooth paste. (It should be scoopable, not spreadable.)
 - Scoop the dough onto the prepared baking sheets with a #100 scoop (small ice cream scoop) about 1½ inches apart. Top with a sprinkling of chopped almonds. Let the cookies dry at room temperature for 1 hour (this gives the cookies their crisp crust).
 - When you are ready to bake, preheat the oven to 400° F.
 - Dust the cookies with confectioners’ sugar.
 - Bake until evenly golden brown, 12 to 15 minutes. Rotate and switch the baking sheets as necessary for even baking.
 - Allow the cookies to cool for a minute on the baking sheets and then transfer, using a spatula, to a cooling rack and allow to cool completely. Store the cookies in an airtight container.
