Recipe: Sour Milk Biscuit

Rub into a quart of sifted flour a piece of BUTTER the size of an egg, one teaspoonful of salt; stir into this a pint of sour milk, dissolve one teaspoonful of soda and stir into the milk just as you add it to the flour; knead it up quickly, roll it out nearly half an inch thick and cut out with a BISCUIT-cutter; bake immediately in a quick oven.

Very nice BISCUIT may be made with sour cream without the BUTTER by the same process.
