If tinting dough, add food coloring. For chocolate dough, reduce flour to 4 1/2 cups and add 2/3 cup cocoa. For hand-formed cookies, transfer to an airtight container. For rolled and cut cookies, divide dough in half, form into 1-inch-thick slabs, and cover tightly with plastic wrap. For sliced cookies, use parchment paper to roll dough into logs. Chill dough at least 2 hours. And chill formed cookies 20 minutes before baking at 350 degrees F on parchment-lined baking pans 10 to 15 minutes, depending on cookie size. For tinted-dough cookies, reduce oven temperature to 325 degrees F and bake 12 to 18 minutes.Nutritional information is based on 1 two-inch round cookie."^^<http://www.w3.org/2001/XMLSchema#string>
