About sour cream Edit
Sour cream or soured cream is a dairy product rich in fats obtained by fermenting a regular cream by certain kinds of lactic acid bacteria. The bacterial culture, introduced either deliberately or naturally, sours and thickens the cream. Although sour cream is only mildly sour in taste, its name stems from the production of lactic acid by bacterial fermentation, a process referred to as "souring".
Used primarily in the cuisines of Europe and North America, sour cream is often used as a condiment. It is a traditional topping for baked potatoes, added cold along with chopped fresh chives. It is used as the base for some creamy salad dressings and can also be used in baking, added to the mix for cakes, cookies, American-style biscuits, doughnuts and scones. It can be eaten as a dessert, with fruits or berries and sugar topping.
