Grease baking sheets; set aside

In a large bowl, combine flour, sugar, baking powder, and salt. Cut in shortening using a pastry blender until mixture resembles coarse crumbs. Make a well in the center of the flour mixture. Stir together the sourdough starter and milk; add to flour mixture. Using a fork, stir just until moistened. Drop dough from well-rounded tablespoons onto prepared baking sheets.

Bake at 375º for 15 to 18 minutes or until golden brown. Remove from oven and cool.
