Make Classic Sugar Cookies with 1 cup granulated sugar total (omit confectioners') and lemon zest instead of orange; omit baking powder. Chill. Pulse 1/4 cup granulated sugar and 1 tablespoon lemon zest in a food processor. Roll dough into two 1-inch-thick logs and roll in the lemon sugar. Freeze logs 20 minutes, then slice 1 inch thick. Bake 20 to 25 minutes at 325 degrees.
