1. Cut lard into flour using a pastry blender or two forks, and add the pinch of sugar. Add enough buttermilk to make a soft dough and knead until smooth (do not over knead as this will lend a tough biscuit).
2. With floured hands pinch off a bit of the dough and roll into a ball, lightly flatten in a greased iron skillet or pan. Bake in a preheated 425 degree oven for 15-18 minutes. Brush with melted butter when removed from the oven.
