Another plus is using yogurt in any recipe that calls for buttermilk. Not only is it healthy and economical, Yogurt works better than buttermilk in recipesPlus, especially if I get a piima culture going, it is much less expensive than buying from the store. A single serve cup of live active greek yogurt is almost a dollar. A gallon of milk is around 2.50. I can make a lot of single serve yogurts out of that.
