If a recipe calls for Buttermilk and you have none on hand use this homemade version. It is much cheaper then buying it and works just as well. NOTE: Please make sure all ingredients are at room temperature or the mixture wil curdle on you.


  1. Pour milk in a 32 oz measuring cup.
  2. Slowly stir in vinegar and mix well.
  3. Add water, slowly while stiring to fill to the 32 oz mark; mix well.
  4. Refrigerate.

Used this buttermilk when making mashed potatoes and they tasted great. I like that this recipe saves me money and works as well as real buttermilk. Have all the ingredients on hand so I can make it anytime I need buttermilk. Thank you for sharing this recipe! Made and reviewed for KK's Recipe Tag Game.
