Heat the oven to 300 degrees F. Mix sugar salt and butter together until fluffy, then put in flours until the dough is stiff. Roll into a log and cut pieces 1/3 inch thick before putting on a baking sheet. In 30 minutes it will be done. The ingredients are 1/2 tsp. salt, 3/4 cup of unsalted butter, 1/4 cup confectioners’ sugar, 3/4 cup of all purpose flour, 3/4 cup of cake flour and 1 1/2 tsp. of sugar. Good luck and have fun.
