1 1/3 cups all-purpose flour
1/8 teaspoon salt
2/3 cup butter, cut up
1/3 cup granulated sugar
1 large egg yolk, lightly beaten
1/2 teaspoon vanilla extract
Grated zest of 1 lemon
1/3 cup confectioners' sugar

Preheat oven to 350°F.

Line a cookie sheet with parchment paper. In a large bowl, sift the flour and salt. Use a pastry blender to cut in the butter until the mixture resembles coarse crumbs.

Mix in granulated sugar, egg yolk, vanilla, and grated lemon zest to form a smooth dough. Form the dough into 1 1/2 x 1/2 inch logs and place 1 inch apart on cookie sheet, flattening them slightly.

Bake for 10-12 minutes, or until just golden. Transfer to wire racks to cool. Dust with confectioner's sugar.

Makes 16 cookies.
