Add the diced country ham to the biscuit dough at the same time as you add the buttermilk. Stir with a wooden spoon. Dump the dough on a flat surface & form into a rectangle with your hand, just like you do in the recipe for Mama's Biscuits. Cut into 8 or 10 squares using a pizza cutter. If you want to have round biscuits, spin them with both hands on a flat surface to give them a circular appearance.Place in a cast iron skillet if available - if not, use a casserole dish or cake pan. Drizzle about 3 tablespoons of melted butter onto the uncooked biscuits. Cook in an oven preheated to 500 degrees for 12-15 minutes. Brush the tops with a few more tablespoons of melted butter.
