Add milk. Stir until the dough clings together. You want it wet, but not sticky.
Place the dough on a lightly floured surface, and knead about 4 or 5 times.
Pat the dough to about 1 - 2 " thickness. Cut with your desired cutter.
Remove the pan from the oven. The shortening should be completely melted, and covering the bottom of the pan. Place cut biscuits into the pan.
