1 stick (8 tablespoons) salted butter, softened enough to be pliable
Instructions
Adjust oven rack to lower middle position and heat oven to 350 degrees.
Mix flour, ¼ cup sugar, and lime zest in a medium bowl. Add butter; beat (or simple mix with hands) to form smooth dough.
Drop dough by generous teaspoons onto a parchment (or silpat-lined) cookie sheet; roll into balls. Bake until cookie bottoms are golden brown, about 15 minutes. Transfer cookies to a wire rack to cool completely.
Place remaining sugar in a quart-size zipper-lock bag. Working a dozen at a time, drop cookies into sugar; shake to coat. Serve. (Can be stored in an airtight tin up to 1 week.)
