Is Buttermilk Dairy Free?

Buttermilk is a dairy product resulting from the fermentation of milk, typically cow's milk. It has a tangy taste and a slightly thicker consistency than regular milk due to the presence of lactic acid bacteria, which are responsible for its characteristic flavor and acidity. Buttermilk is commonly used in baking, cooking, and marinades, and it plays a critical role in recipes due to its ability to tenderize and add moisture.
