2Cookie Batter: Cream sugar and shortening together. Add egg, vanilla and the milk till combined. Add flour, baking soda, and cream of tartar. On a floured surface roll out the dough and cut into disks. (my dad always use a water glass to cut out the cookies). Fill the center of the disks with a teaspoon of raisen mixture then place another disk of dough on top to cover then crimp the sides of the cookie to prevent leaking. Bake at 350 degrees for 10-12 minutes or until lightly golden brown. These cookies freeze exceptionally well.
