No, it isn’t. Sour cream is an ingredient that was invented in Eastern and Central Europe that is made when dairy cream is mixed with bacteria that produce lactic acid. This creates a thick tart-like substance. It is used for dips, to thicken sauces, garnish soups and potatoes, and come up with a creamy frosting. Usually, it is used just when a meal is about to be ready.
