So we cooked some corn a couple weeks ago, left extras in the oven. Fast forward to tonight, I discovered we left it there. The pan it was sitting on was white as a ghost. Tossed that pan.
Is it safe to throw new food in there and cook it? I already got a cassarole baking now. Is it ruined? Only thing I can think would be mold spores, but 400F should kill them.
p.s. I'm paranoid about this stuff, sorry.
