How to Make Buttermilk at Home

Making buttermilk at home is a simple process. Here’s how you can do it:


  • Milk (whole or 2%): 1 cup
  • Lemon juice or White vinegar: 1 tablespoon


  1. Prepare the Milk:
    • Pour 1 cup of milk into a bowl. You can use whole milk or 2% milk.
  2. Add Lemon Juice or Vinegar:
    • Add 1 tablespoon of lemon juice or white vinegar to the milk.
  3. Stir and Let it Rest:
    • Gently stir the mixture to ensure the lemon juice or vinegar is well distributed.
  4. Wait for Curdling:
    • Allow the mixture to sit at room temperature for about 10-15 minutes. During this time, the acid (from the lemon juice or vinegar) will cause the milk to curdle and thicken.
  5. Check for Curdling:
    • After 10-15 minutes, you should see the milk curdle, and it will have a slightly thicker consistency.
  6. Stir Again (Optional):
    • If needed, give it a gentle stir to ensure proper curdling.
  7. Use or Store:
    • Your homemade buttermilk is ready to use! You can use it in recipes that call for buttermilk.


  • You can adjust the quantities based on your requirements. For example, you can use half a cup of milk and half a tablespoon of lemon juice or vinegar if you need a smaller amount of buttermilk.
  • If you don’t have lemon juice or white vinegar, you can also use other acids like apple cider vinegar.
  • Store-bought buttermilk can also be used as a starter culture. Simply add a small amount (about 2 tablespoons) of store-bought buttermilk to your milk and follow the same process.

Homemade buttermilk is a great ingredient for baking and cooking. It’s a versatile dairy product that can be used in various recipes, from pancakes to salad dressings.
