Everything you ever wanted to know about Buttermilk all in one place. I’ll teach you what it is, why you use it, and how to make it at home.



  • 1 tablespoon white vinegar OR lemon juice
  • 1 cup milk


  1. Measure the vinegar or lemon juice into your measuring cup and then fill it the rest of the way with your milk (so you’ll actually need a tablespoon less of milk than a full cup because that 1 tablespoon is your vinegar or lemon juice).
  2. Gently stir the mixture together.
  3. Let mixture sit for 5 minutes.
  4. Use in your recipe in place of the buttermilk called for.


  • Here’s the amounts you’ll need for common recipe amounts. 


Vinegar or Lemon Juice

¾ cup

2 ¼ teaspoons

⅔ cup

2 teaspoons

½ cup

½ tablespoon OR 1 ½ teaspoons

⅓ cup

1 teaspoon

¼ cup

¾ teaspoon

  • Another method is to whisk 1/4 cup milk into 3/4 cup plain yogurt. This will create a nice and thick buttermilk substitute.
  • You can also use milk and sour cream as a buttermilk substitute. Whisk together 3/4 cup sour cream and 1/4 cup milk until you get a thicker consistency that resembles buttermilk.
