How to Make Homemade Buttermilk

  1. Measure milk: Measure out 1 cup of whole milk.
  2. Stir: In a small bowl or measuring cup, add 1 tablespoon of white vinegar or fresh lemon juice.
  3. Pour: Pour the white vinegar or lemon juice into the cup of whole milk.
  4. Stir: Stir the mixture gently to combine. You will notice that the milk starts to curdle slightly and thicken. This is what you want to achieve the buttermilk-like consistency.

  6. Use: After resting, your homemade buttermilk is ready to use in your favorite recipes. Try it in pancakes, biscuits, salad dressings, and more!
