I remember when I was a kid my mom used to drink a lot of buttermilk. She would make clabbered milk from raw milk. It was common for people in the south to drink it with pepper or eat it for breakfast by adding cinnamon and sugar or molasses. It had a thin yogurt texture to it with a very distinctive sour flavor. I never could figure out how she could like it! As I have gotten older and my taste buds have changed I can drink butter milk now. This tutorial is how to make a buttermilk substitute for recipes calling for buttermilk. I read that making this type of substitute will not change the flavor of the baked goods but it is a good to use in a pinch. Yogurt would make a better substitute because of the flavor if you have it on hand.
