Preparation

• Use the back of a large spoon or a rubber spatula to mash the 1-1/2 Tbs. granulated sugar into the dough until it’s evenly dispersed. On a lightly floured surface, shape the dough into a log about 6 inches long and 1-3/4 inches in diameter. Wrap the log in waxed paper or foil. Refrigerate for at least 2 hours, but preferably overnight.
• Put the 1/4 cup turbinado (or granulated) sugar on a flat surface such as a tray or clean countertop. Roll the log of dough in the sugar, pressing so the sugar adheres. Cut the log into 1/4-inch slices and arrange them at least 1 inch apart on an ungreased or foil-lined cookie sheet. Position a rack in the center of the oven and heat the oven to 350°F. Let the cookies sit at room temperature while the oven heats. Bake until the edges are golden brown, 12 to 15 minutes, rotating the pan from front to back about halfway through baking. Let the cookies sit on the sheet for a minute or two before transferring them to a rack with a metal spatula. Let cool completely before storing airtight.

Make Ahead Tips

If you’re not serving the cookies within a day or two, freeze them in airtight containers and defrost at room temperature.
