Recipe: Vinegar Biscuits

Take two quarts of flour, one large tablespoonful of lard or BUTTER, one tablespoonful and a half of vinegar and one teaspoonful of soda; put the soda in the vinegar and stir it well; stir in the flour; beat two eggs very light and add to it; make a dough with warm water stiff enough to roll out, and cut with a BISCUIT-cutter one inch thick and bake in a quick oven.
