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.
