Buttermilk意思

Buttermilk is a type of fermented dairy product that is traditionally the liquid that remains after the fat has been churned from cream to make butter. However, in modern times, buttermilk is often commercially produced by adding lactic acid bacteria to regular milk, which thickens and slightly sours the milk. This process gives buttermilk its characteristic tangy flavor and thick consistency.

Buttermilk is lower in fat than regular milk because the fat has been removed during the butter-making process or is reduced in commercially produced buttermilk. It is a good source of calcium and other nutrients found in dairy products.

Buttermilk is commonly used in baking, especially in recipes for quick breads, pancakes, waffles, and biscuits, as it can help to make these foods tender and fluffy. It is also sometimes used as a marinade for meat or as a ingredient in salad dressings and sauces.

In some parts of the world, buttermilk is also used as a drink, often served cold as a refreshing beverage. It is a staple in the cuisine of the Southern United States, where it is used in many traditional dishes.
