Sour Cream
Prep time: 
Fermentation time: 
Yield: 1 pint
 
Ingredients
  • 8-10 fluid ounces (250ml) good quality heavy whipping cream (avoid Ultra-pasteurized)
  • 1-2 Tablespoons (15-30ml) sour cream
Instructions
  1. Let heavy cream come to room temperature (or up to 75°F/24°C).
  2. Add cream to a pint sized (or larger) jar.
  3. Spoon sour cream and mix thoroughly.
  4. Secure jar lid and shake gently for 1-2 minutes until cream thickens. Stop before it "breaks", otherwise you'll end up making butter and buttermilk!
  5. Burp lid, then let it ferment at room temperature (ideally 75°F/24°C) about 24 hours.
  6. Stir contents and taste. If it needs more souring, let it ferment another day or two.
  7. Store in refrigerator with lid on.
