How to Make It
Preheat oven to 300°. Beat granulated sugar and butter at medium speed with a heavy-duty electric stand mixer until creamy. Add egg yolks, 1 at a time, beating until blended after each addition. Whisk together flour and cornmeal; gradually add to sugar mixture, beating just until blended. Roll to 1/4-inch thickness on a heavily floured surface. Cut with a 3 1/4-inch star-shaped cutter; decorate with sparkling sugar. Place 2 inches apart on lightly greased baking sheets. Bake 14 to 16 minutes or until lightly browned. Cool completely on wire racks (about 20 minutes).
