How Do You Make Buttermilk?
To make buttermilk, you will need milk and an acid like lemon juice, vinegar, or cream of tartar. For every cup of milk, add one tablespoon of the acid of your choice. Let the mixture sit for about 10-15 minutes so that it can curdle and thicken. The resulting mixture can be used in recipes calling for buttermilk. Alternatively, you can use whole milk yogurt mixed with a little water as a substitute for buttermilk.
