I would have bacteria and, yeah, it would grow in what we call the danger zone, which is typically between 40 and 140. But if I'm getting something out of my refrigerator where it's been basically pretty clean and I'm putting it on my counter, what exactly is going to happen in that amount of time that going into a hot oven isn't going to kill?

Alton BrownYou know, [skin] happens at the gravy boat stage - right? - or this happens when you're trying to keep it warm. So the way that I avoid this is I keep my gravy - the second it's done, I put it in a thermos, which will keep it hot and will prevent air from getting to the surface. And I keep it there till the last moment. The last thing that goes out to the table is the gravy, and I pour it out of the thermos and immediately move it in.
