Sometime in the past little while, the sheet of aluminum foil in the toaster oven disappeared, perhaps because it had already seen a few too many droplets of over-toasted cheese. In my infinite wisdom, I did not see fit to replace it before toasting my cheesy muffins.
The toaster dinged merrily after a few minutes, and I wandered over to retrieve my prize -- and found to my everlasting shock that the interior of my toaster oven was merrily blazing away!
Some of the cheese had dripped on the metal piece covering the heating element, and lo and behold, the cheese started flaming away like a despot's oil well in the face of an invading force.
I extinguished my toaster oven and retrieved my muffin. (The muffin was still edible.)
I can cook. I can cook.
Sometimes the kitchen just doesn't like me. Now that the cheese has been scraped off the inside of the toaster oven, it does operate perfectly nicely.
