to ungreased baking sheets. Bake them dozen to 15 minutes, exchanging the position of the sheets on the racks from top to bottom and from front to back at the halfway point, until the cookies are crisp and lightly colored. For the coating, mix the sugar, cinnamon, and cloves in a wide shallow dish (like a pie plate). Carefully dredge the cookies in the spiced sugar while they are warm. Cool completely on a rack. Store at room temperature in airtight tins.
