OKay, folks, in response to the "12 year old burger" thread, I've decided to do a little independent study. On 12/14 at 5:30pm, I purchases two McDonald's plain hamburgers. I placed one in the refrigerator in a sealed container, and placed the other on my counter. I will report back to you in a regular basis what's been happening to them. As a control group, I also made a homemade hamburger using storebought generic burger buns and generic beef patties. Okay, I made three, ate one, and used the others as a control, but whose counting? For the record, none of the burgers in this test have any extras: no cheese, ketchup, onions, etc. (this was special order, since the standard burger at McDonald's comes with ketchup, mustard, and onions.) Also, at 12/15 at 6:00am this morning, I will lay out a slice of generic store bought bread on my counter, and place another one in a sealed container in the refrigerator. Let the games begin.
