Preheat oven to 400 degrees. In a bowl, mix the shortening, sugars, egg, vanilla and milk until fluffy.  Measure flour by sifting and mix dry ingredients together.  Add this to the sugar mixture and stir thoroughly.  Shape dough into 1" balls.  Place balls 2" apart on ungreased baking sheet.  Flatten to 1/8" thick with a greased fork dipped in sugar.  Bake 8 to 10 minutes or until brown.
