The Easiest Way to Make Buttermilk
Serves: ½ gallon
  • Just under ½ gallon of milk
  • 1 cup buttermilk
  1. Add buttermilk to regular milk.
  2. Shake well.
  3. Allow milk/buttermilk mixture to sit on the kitchen countertop for 12-36 hours or until the milk has become cultured.
  4. You will be able to see that the new batch has turned into buttermilk by tilting the jar. If the contents of the jar have thickened and "plop" over when you tilt the jar, your buttermilk has formed! If the mixture is still runny like milk, continue to let the jar sit on the countertop.
  5. Once the buttermilk has formed, transfer the jar to the fridge, using as needed.
  6. Save one cup of buttermilk to use in subsequent batches, following the directions above for additional jars of buttermilk.
