10 Food Facts That Will Make You Question Everything You Believe In

A common kitchen debate is whether or not you should refrigerate butter, and it's understandable to be confused. It's true that butter is dairy, but it doesn't expire as quickly as other products because it's mostly fat. And salted butter is less susceptible to bacteria than unsalted butter because of its sodium content. You can leave salted butter out of the fridge for about two weeks as long as your kitchen is 70°F or colder, but it should be kept in a butter crock or a similar airtight container. Unsalted butter should be kept refrigerated all the time.
