Buttermilk

Buttermilk is a fresh, slightly sour dairy drink that is produced when milk is fermented by lactic acid bacteria or as a by-product of butter making. It has a soft, creamy texture with a distinctive sour taste. Buttermilk is often drunk chilled as a refreshing drink and can also be used in baking recipes such as pancakes and bread, because it provides an airy structure and mild taste.
