Sift a pound of flour into a pan, and rub into it two ounces of butter; mix in the whites only of three eggs, beaten to a stiff froth, and a table-spoonful of strong yeast; add sufficient milk to make a stiff dough, and a salt-spoonful of salt. Cover it and set it before the fire to rise. It should be light in an hour. Then put it on a pasteboard, divide it into rolls, or round cakes; lay them in a floured square pan, and bake them about ten minutes in a quick oven.
