SOUR MILK COOKIES

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.
