Does flour expire?
Actually, yes, especially self-rising flour, which can lose its self-rising properties quickly if you store it somewhere warm, like in a tin right beside your stove. If you keep flour somewhere that is not airtight for more than 6 months or so, your baking products will not taste as fresh or rise as well. You don’t want to keep all-purpose flour for more than 6 months, unless it has been kept in the frige or freezer. It is best to keep flour of any kind in your freezer, believe it or not. You can keep it for up to a year that way. Check this site for more info (scroll down a little to “storing flour”: http://muextension.missouri.
