Use 1/2 cupful sugar and 1/2 cupful molasses instead of 1 cupful of sugar.
Increase the baking soda to 1/2 teaspoonful.
For flavoring use 1 teaspoonful ginger and 1 teaspoonful allspice.
Since the molasses furnishes some moisture, it is usually necessary to add more flour or decrease the sour milk or cream.
COOKIES WITH RAISIN FILLING
Prepare Sour Cream Cooky dough. Roll the dough into a thin sheet and cut it into rounds. Spread half of the rounds with a thin layer of Raisin Filling (see below). Then cover each round with another piece of dough. Press the edges together. Place on an oiled baking sheet and bake in a moderate oven.
RAISIN FILLING
1/2 cupful corn sirup 1 cupful seeded raisins 1/4 teaspoonful salt
Cook these ingredients until the mixture is thick enough to use as cake filling.
One fourth cupful of chopped nuts may be added. One egg may also be added to the mixture just before removing from the fire.
