Interesting facts about sour cream

sour cream

Sour cream or soured cream is a dairy product.

It is made by fermenting regular cream with certain kinds of lactic acid bacteria.

The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream.

Its name comes from the production of lactic acid by bacterial fermentation, which is called souring.

Sour cream’s history dates back to the first half of the 20th century, and is associated with the cooking traditions of Eastern Europe, Russia, Ukraine and Germany.

Originally, making sour cream involved allowing fresh cream to sour naturally. The bacteria that developed during fermentation thickened the cream and made it more acidic, a natural way of preserving it.

Today, commercial sour cream is made from light cream of from 18 to 20 percent milk fat which, after pasteurization, is inoculated with lactic-acid-producing bacteria. The cream is ripened 14 to 16 hours at 72°F (22°C), then chilled and aged from 12 to 48 hours. The bacterial action thickens the cream into a semisolid and adds a tangy flavour.
