Homemade Cultured Buttermilk: Printer Friendly Version!


  • 1/4 to 1/2 cup cultured buttermilk (from the store or home cultured)
  • 1 to 2 quarts skim,1%,  2%, or whole milk from the store or raw milk

Also needed:

  • 1 clean, dry quart or half gallon jar with a tight fitting two piece lid.

Okay.  Ready?  If you blink you’ll miss how to do it.

Pour buttermilk (1/4 cup for a quart jar or 1/2 cup for a half gallon jar) into your clean jar.  Top off the jar with your plain milk.  Tightly screw lid to the jar and shake vigorously for 1 minute.  Place in a warm (but not hot) area out of direct sunlight.  Let it sit there for 12 to 24 hours, until thickened.  Refrigerate when thick.  Use within two weeks.  If you re-culture this regularly, you can carry on re-culturing indefinitely.  I always feel like I’m stickin’ it to the man when I do homemade stuff like this.  Who doesn’t love beating the system?
