This is the old-time recipe from our grandmamas. There is no real measurement in this for the shortening. Wonderful and tasty heavy biscuit from the old times. Great with homemade sausage gravy. Always always always use White Lily® flour for the fluffiest biscuits. I usually don't always use all of the buttermilk. I seem to usually have just under a 1/4 cup leftover.
