Sour cream

Sour cream or soured cream is a food made from cream that has been fermented. It is thicker than cream, and has a sour taste from lactic acid. Sometimes when bought from a store it has gelatin, rennet, or other things added to make it thicker. Like many other dairy products, it must be kept refrigerated.
