Butter is a dairy product that is widely used in cooking and baking. It is made by churning cream or milk until the fat separates from the liquid, resulting in a smooth and creamy substance. Butter is a versatile ingredient that can be used in a variety of dishes, from savory to sweet. It is commonly used as a spread on bread or toast, as well as in sauces, pastries, and desserts. Butter is also a good source of fat-soluble vitamins and essential fatty acids, making it a nutritious addition to any diet.
