I can’t tell you how many times I’ve wanted to make something that requires buttermilk and I don’t have any on hand. Buttermilk just isn’t something I keep around regularly. This is a good trick to know and works as a great replacement for buttermilk. It works with both milk and soymilk. I have not tried it with almond milk but I think it would work the same (?).
1 cup milk or soymilk
1 tbsp white vinegar
Stir vinegar into milk and allow to sit for several minutes to curdle and thicken. Use as directed in any recipe for buttermilk.
