A lot of the old time recipes call for baking soda instead of baking powder when you are using vinegar or sour milk.
1 teaspoon baking powder equals 1/4 teaspoon baking soda plus 1/2 teaspoon cream of tartar, if you are ever out of baking powder this is the substitute. I learned that in Home-ec in the 8th grade. Those were the days of cooking from scratch......
