This is a recipe from Bon Appetit February 2012. It takes supermarket buttermilk and elevates it to a Liquid Gold level. Chill time is cook time.


  1. Mix all ingredients in the mason jar.
  2. Cover jar.
  3. Let stand in a warm place until the buttermilk thickens and coats the side of the jar when tipped.
  4. This will take 24-36 hours.
  5. Keep chilled for up to 2 weeks.
