What is the difference between Milk and Buttermilk?

Buttermilk is fermented milk with a slightly sour taste, whereas milk is the creamy white beverage, which is produced within the mammary glands of cows. Cow's milk is used by human beings in many different products such as chocolates, ice creams, yogurt, and butter.

Buttermilk is collected when the fat has been removed from the milk to make butter. It is made from the end products of butter through a process known as churning. Buttermilk is much lower in fat and calories, and it is easier to digest than milk. It tastes tangy and sour. Buttermilk is incorporated into pancakes, bread, onion, salad dressing, chicken marinade, and mashed potatoes.
