Crunchy in texture from cornmeal, the cookies have a subtle citrus flavor from the addition of lime zest. The dough can be wrapped well and frozen for up to 1 month.
In a bowl, whisk together the flour, the 3 tablespoons cornmeal, and the salt. In a large bowl, using an electric mixer on medium-high speed, beat together the butter and confectioner’s sugar until light and fluffy, 2–3 minutes. Beating on low speed, slowly add the flour mixture and continue to beat until almost incorporated, scraping down the sides of the bowl as needed
