Sour cream is an acidic-tasting cream equivalent to unpasteurised cream that has turned and is frequently added to soups, dips and sauces.
You can make your own sour cream by adding 2 tablespoons of buttermilk to 2 cups of fresh cream and allowing the mixture to sour at room temperature, without disturbing it, for at least 24 hours. Homemade sour cream will keep for 3 days in the refrigerator. When cooking with sour cream add it to hot food at the last minute and gently reheat without allowing it to boil or it may separate.
