How Do You Make Buttermilk With Vinegar?
To make buttermilk with vinegar, take a measuring cup and add 1 tablespoon of white vinegar or apple cider vinegar per 1 cup of milk. Let it sit for 5-10 minutes until the milk begins to curdle and thicken. Stir it gently and use as needed in your recipe. This can be used as a substitute for buttermilk in most recipes.
