I love to use buttermilk but it is so expensive. So, after some research... I started making my own. Measurements can vary. Use approximately 1 part buttermilk to 3 parts milk.

I love using buttermilk when cooking and baking. I decided to try this with skim milk powder. It didn't work at first, the problem was that the house was a little extra cool. I put it in the oven on the bread proof setting (100 F). It got so nice and thick with that lovely sour smell. Thanks so much! I read somewhere that you can use buttermilk to culture your own sourcream too, I will have to try that as well! Thanks so much, I hope to never have to buy buttermilk again!


  1. Add buttermilk and milk to a clean glass quart jar. Cover.
  2. Let sit in a warm place for about 14 hours; the time will vary depending on how warm your house is and it can take as long as 24 hours.
  3. Check every few hours after the first 12 - 14. When buttermilk reaches a nice thick consistency, place in fridge to cool down and store.
  4. From this culture you can continue to make your own continuous supply of buttermilk.
