Twinkies and McDonald's Hamburgers that don't Rot

Different kinds of aging burgers

It is an urban myth that Twinkies don't rot; even Wall-E knows that.

Kenji Lopez-Alt did a test. He took different kinds of hamburgers and left them on the counter. It is pretty entertaining, so I thought I'd put up a link to it.

He showed that smaller portions dried out, and "mummified," before they were infested by mold and rotted. Larger burgers did rot.

It may also be true that the commercially prepared food had fewer mold spores to start with, and that delayed onset of rot.

Twinkies are supposed to last a month until they get stale and tough. They supposedly last a long time because of they are non-dairy, but no one knows.
