Plain Cookies.
Ingredients: One cupful of butter (or half butter and half lard), two cupfuls of sugar, one cupful of milk, two eggs, about a quart of flour (cookies are better to have no more flour than is necessary for rolling them thin without sticking), three tea-spoonfuls (not heaping) of yeast-powder, or one tea-spoonful of cream of tartar and half a tea-spoonful of soda.
Sour milk can be used, when add the half tea-spoonful of soda, and omit the cream of tartar. Bake in a quick oven.
