Scottish Shortbread

Modified from Cookies Cookbook

3/4 cup all purpose flour

1/2 cup cornstarch

1/4 cup sugar, plus some extra for sprinkling

1/2 cup unsalted butter, chopped, room temperature (unsalted really DOES matter)

Preheat oven to 325. Sift flour, cornstarch, and sugar in a mixing bowl. Rub butter into the flour mixture until it binds and you can knead it into a soft dough. Put dough in mold or mold by hand. Put on baking sheet.

Bake for 35-40 minutes or until pale golden in color.

Sprinkle with sugar and cool on baking sheet. They taste best the NEXT day, not right after.
