Ingredients:

  • 2 cups heavy cream
  • 2 tablespoons cultured buttermilk

Instructions:

  1. Clean your jar. Wash a glass pint jar with hot, soapy water and dry it completely.
  2. Combine the dairy. Pour 2 cups heavy cream and 2 tablespoons cultured buttermilk into the jar.
  3. Seal and shake. Put the lid on tightly and give it a vigorous shake for 10 seconds to ensure the cultures are evenly distributed.
  4. Vent the jar. Remove the solid lid and replace it with a coffee filter or cheesecloth. Secure it with a rubber band.
  5. Find a spot. Place the jar in a warm, draft free area of your kitchen out of direct sunlight.
  6. Wait 24 hours. Let it sit undisturbed. You will see it begin to thicken and look slightly opaque. Note: If your house is over 75°F, check it at 12 or 15 hours.
  7. Check the consistency. After 24 hours, the cream should be the thickness of a loose yogurt.
  8. Seal and chill. Replace the breathable cover with a solid lid and refrigerate for at least 12 hours.
  9. Stir before using. Once chilled, it will be thick and spoonable. Give it a gentle stir until it looks silky and uniform.
