What is buttermilk?
Traditional buttermilk is a non-fat, thin liquid that is left after churning butter from cream. Buttermilk is rich in taste and has helpful cultures that develop when cream is left at room temperature for few hours.
Buttermilk today is simply curdled milk. Usually not a by-product of churning butter from whole milk, but adding lactic-acid producing bacteria cultures to pasteurized milk. The lactic-acid producing bacteria make buttermilk slightly sour and prevents unwanted bacteria growth.
