Butter is made by churning cream, which is the fatty layer that rises to the top of milk.

Cow's milk is the most widely used type of milk for butter production due to its availability and high fat content.

Churning involves agitating cream to cause the fat globules to clump together and form butter.

Butter typically contains a high percentage of fat, usually ranging from 80% to 85%.

Salt is added to butter to enhance its flavor and act as a preservative, extending its shelf life.

Cultured butter is made using a lactic acid culture, which gives it a distinctive tangy and slightly sour flavor.

Sweet cream butter is made from fresh cream and contains salt, while unsalted butter is made from fresh cream without the addition of salt.

Unsalted butter is preferred for baking and pastries as it allows for better control over the flavor and salt content of the final product.

Creaming is the process of whipping butter to incorporate air, resulting in a lighter and fluffier texture.

Whipped butter is made by whipping butter to incorporate air, resulting in a spreadable consistency that is ideal for use as a topping.

Butter should be stored in the refrigerator at a temperature between 35°F and 40°F (2°C and 4°C) to maintain its quality and prevent spoilage.

Unopened butter can typically be stored in the refrigerator for 3-4 months before it starts to deteriorate.

Opened butter should be used within 1-2 weeks to maintain its quality and prevent spoilage.

Butter is used for a variety of purposes in cooking and baking, including spreading on bread, frying, baking cakes and pastries, and making sauces and gravies.

While butter contains some essential nutrients, there is no strong evidence to support specific health benefits from consuming butter in moderation.
