Sour cream is a dairy product made by fermenting regular cream with lactic acid bacteria, which thickens and sours it. The fermentation process produces lactic acid, giving sour cream its characteristic tangy flavor. Sour cream can be used as a condiment, a base for dips and dressings, or an ingredient in various recipes, including soups, stews, and baked goods. It typically contains around 18-20% milk fat.
Many manufacturers produce sour cream, with Daisy Brand being a popular choice in America. Other notable manufacturers include Prairie Farms Dairy, Hiland Dairy, and Cacique Foods. The ingredients in sour cream typically include cultured cream and sometimes additives like modified food starch, whey, and various gums to enhance texture and shelf life. Some brands offer "all-natural" options with minimal ingredients. You can also find reduced-fat, nonfat, and even dairy-free (vegan) versions made from nuts or soy. Sour cream is widely available in most grocery stores and supermarkets. The price of sour cream varies depending on the brand, size, and type, but typically ranges from $1.69 for an 8-ounce container to $3.29 for a 16-ounce container.
