Ingredients

  • 8 ounces Whipping Cream NOT "heavy" whipping cream. You want whipping cream that has only 4.5 grams of fat.
  • 2 tablespoons Cultured buttermilk See "Recipe Notes" below.

Instructions

  • Pour whipping cream into a clean jar.
  • Add buttermilk to cream.
  • Stir the cream and the buttermilk with a clean utensil.
  • Put a lid on the jar and leave the lid loose. Do not tighten the lid. If the jar you are using does not have a lid, another option is to cover the lid of the jar with a clean dish towel or new cheesecloth.
  • Place the jar in a warm spot in your kitchen between 68-78°F, out of direct sunlight, and allow the cream to culture for 12-24 hours until the desired tangy taste and thickness is achieved.
  • If you are using milk kefir to culture your cream, follow the same instructions above.
  • If you are using yogurt to culture your cream, you will need to place your jar in a warmer place that can maintain a temperature of approximately 110°F. This place may be in an oven that is turned off but has the electric light or pilot light turned on.
  • Refrigerate the sour cream in a jar with a tight-fitting lid. It should stay fresh for approximately 2 weeks.

Notes

Buttermilk:  You can use cultured whole milk buttermilk that is available from most grocery stores, or you can use real cultured buttermilk that is a by-product of making cultured butter.

Buttermilk Substitutions:  If you do not have access to either buttermilk variety described above, you may use 2 tablespoons of plain milk kefir (homemade or store-bought), or 2 tablespoons of plain whole milk yogurt (homemade or store-bought).
