Can You Use Expired Butter?

Perishables come with an expiration date, but not everything goes bad by that date. As one of the most popular ingredients, butter can outlast its expiry date by months and even a year. Butter is a dairy product made from the fat and protein components of milk and cream. It is used at room temperature as a spread, and also used as an ingredient in baking, sauce making, pan frying, and other cooking procedures.
