Preheat oven to 325 degrees F.
Cream together sugars, shortening, egg, vanilla, and salt in a large bowl.
Add the flour and baking powder. Add 1 tablespoon of water and continue mixing until the dough forms a ball.
Roll the dough into ¾-inch balls and flatten slightly onto a lightly greased cookie sheet. Bake for 15 to 18 minutes or until cookies are light brown.
