Our homemade buttermilk recipe is so easy to make that I make it all the time! Homemade buttermilk can be made with fresh milk or milk that has gone sour. It literally takes me two minutes to throw it together, let it sit overnight and then in the morning I have fresh homemade buttermilk for my pancakes.
3 1/2 cups milk
1/2 cup buttermilk, room temperature
After that, you’ll have a fresh batch of homemade buttermilk! This works great. Save a half cup at the end so you can make a new batch of homemade buttermilk. It keeps going and going!
