Making Buttermilk

Many times I want to make something and it calls for buttermilk and it’s not something I keep on hand.  Some of my friends say they make their own.  I tried it and it works. No matter which you choose to substitute,  stir in the ingredients and let it sit for 15 minutes or so.

I’ve researched and found several ways to use other ingredients.
Another substitution for buttermilk is plain or vanilla unsweetened yogurt. Used in equal measurement. It may be necessary to thin the yogurt with water or milk first (especially if the batter you’re making is relatively thin).
