It might sound strange, but sometimes I make food. Granted, mostly it's just box-food where all the ingredients are supplied and you just add ground meat or something else, but still.
I did this today, and turned on the oven in preparation for my sausage gratin. What I didn't expect was that the oven was used as a temporary food-storage. By the time I noticed, the porridge in the cup had gotten some extra cooking and the plastic ladle had been significantly reduced. Like so:Scraping off whatever molten plastic from the bottom of the oven was not, repeat, not amusing.
I was a bit worried that the fumes from the remaining plastic would affect the food, but so far I'm still at good health.
