Pin Recipe

Equipment

  • 1 Quart size mason jar
  • Small piece of wax paper or cloth to cover jar
  • Rubber band

Ingredients

  • 2 cups raw cream skimmed from raw milk or purchased raw cream
  • 2 tablespoons cultured buttermilk kefir, or existing raw sour cream (starter)

Instructions

Warm the Cream

  • Pour raw cream into a clean glass jar. Let it sit until it reaches room temperature (about 70–75°F / 21–24°C).

Add Culture

  • Stir in the buttermilk, kefir, or sour cream starter until fully combined.

Ferment

  • Cover loosely with a lid or cloth. Let sit at room temperature for 12–24 hours, until thickened and pleasantly tangy.

Refrigerate

  • Once cultured, seal with a lid and refrigerate for at least 6 hours to fully set.

Store

  • Keep refrigerated and use within 1–2 weeks. Save a few tablespoons to culture your next batch.

Notes

For the thickest sour cream, use heavy raw cream with a high butterfat content.
Ideal culturing temperature is 68–75°F.
Flavor becomes tangier the longer it ferments.
Do not use ultra-pasteurized cream; it will not culture properly.
