Centennial Molasses Spice Drops

I am usually not into "spice" cookies, but I really like how these turned out. This recipe comes out of Betty Crocker's Cookie Book. This recipe does have cider vinegar in it. The cook book mentions that vinegar was used in cooking a lot over hundred years ago, even in the baked goods.

So here is the recipe:
2/3 cup butter - I used half shortening and butter
2/3 cup sugar
2 eggs
2/3 cup molasses
3 cups flour
3/4 t baking soda
1/4 t salt
3/4 t cinnamon
3/4 t ginger
1/4 cup cider vinegar - I used apple cider vinegar, it is was I had on hand

Heat oven 374 degrees
Mix butter, sugar, eggs, and molasses. Blend dry ingredients. Alternately add dry ingredients and vinegar. Drop dough by teaspoonfuls on a greased cookie sheet. Bake 8-10 minutes, or until no imprints remain when lightly touched.
