Ingredients

  • 1 cup heavy cream (preferably not ultra-pasteurized)
  • 1 tablespoon buttermilk or plain yogurt with live cultures

Instructions

  1. Pour the heavy cream into a clean glass jar or bowl.
  2. Add the buttermilk or yogurt and stir gently until fully combined.
  3. Cover loosely with a lid or clean kitchen towel.
  4. Let sit at room temperature (around 70–75°F / 21–24°C) for 12–24 hours until thickened.
  5. Check after 12 hours; it should be thick, creamy, and slightly tangy.
  6. Once thickened to your liking, stir gently and refrigerate until fully chilled. It will continue to thicken as it cools.

Notes

  • Regular pasteurized cream cultures more reliably than ultra-pasteurized.
  • Let culture closer to 24 hours for a tangier flavor.
  • Store in the refrigerator for up to 2 weeks.
  • Use a clean spoon each time to maintain freshness.
  • Crème fraîche is more heat-stable than sour cream and resists curdling in warm dishes.
