Take one cup of butter, one cup of sugar, two or three eggs, and
two-thirds of a cup of sour milk. Dissolve a teaspoon of soda in a
little hot water; add part of it at a time to the milk until it foams as
you stir it. Be careful not to get in too much. Mix up soft only using
flour sufficient to roll out thin. A teaspoon of cardamom seed may be
sprinkled into the dough.
