Preheat oven to 450 degrees.
Add some Crisco (or vegetable oil) in an 8 x 8 inch glass pan and place pan in over while it preheats. (You want the Crisco melted and hot before adding biscuits to pan.)
Cut in shortening - just enough to leave small lumps of Crisco.
Stir in enough buttermilk to create a wet and sticky dough - don't stir too much.
Turn out on floured surface. Sprinkle flour on top and lightly knead just until bottom is smooth.
Pat out (don't roll) until dough is approximately 1/2 the height you want your biscuits to be. Cut out with a can (or biscuit cutter, I suppose :D )
Remove pan from oven. Tilt the pan so that all melted shortening flows to one corner of pan. One at a time, dip top of biscuit in melted shortening and place in pan, sides touching.
Bake at 450 until golden brown on top.
