TOD:
The only thing I have ever flambéed is a bag of pretzels that I forgot was stored in my oven when I went to preheat it.
What a mess that was. And the smoke!
One Easter when I was a kid, our parents made Easter "baskets" for us (actually, everything was just put in big bowls, but we didn't care

), but we couldn't find mine, and my mom couldn't remember where she hid it! Well, after a while we gave up looking and she started making breakfast and heated up the oven to keep food warm as she made more, and then shortly thereafter, we started smelling melting chocolate and plastic! THAT is where she hid my bowl (which was a big plastic mixing bowl), in the oven, and which also had plastic "grass," and of course all my chocolate.
To this day, I still check the oven to make sure it's empty before I turn it on!
