I was at a friends house and we decided to cook some chicken things under the grill but then forgot about them and went out. When we came back the kitchen was completely black and we had to scrub soot off the walls.
About 85% of all my cooking is one, big, misadventure -but the most memorable, I guess, have been two fires. One was something I was doing in the broiler, and when I opened the broiler the fire was tall enough to reach the bottom of my top cabinets (nothing serious happened, fortunately). And then there was the fish/toaster-over fiasco, involving having to carry out the toaster oven and put it out in the snow.
Both times my husband pointed out (somewhat condescendingly) that "you don't hide a fire" or "you don't carry one through the whole house" - but it turns out you do! The fires both went out uneventfully (even if I had a couple of scare, crying, children to calm down. )
I'd like to clarify that I've never actually burned down either of my kitchens - only ran the risk of it. I'll never know why that broiler fire that went about six feet in the air didn't catch onto the cabinets. THAT one scared me - and yet was smothered out when I instinctively closed the broiler (aka "hiding a fire", according to my husband). I've got a sister and a bunch of neighbors who've actaully had the fire department come because of kitchen fires.
Just a couple of weeks ago I decided to mix up a box of brownie mix I'd gotten around my son's birthday. In my hurry to get the whole nasty business over and done with, I mixed up the measurements for the oil and water. Actually, they came out OK (after I figured out they wouldn't be ready when the box said they would be ) Apparently, even I can't "misadventure" a boxed brownie mix and have it have much affect.
One time in college, I was in the middle of making brownies when I realized that we didn't have enough cocoa powder. They weren't bad tasting, but they were this odd tan color. We called them "tannies" and ate them anyway!
Another time, my friend made a lemon cake for a party and added in some chartreuse food coloring to make the yellow pop ... only she added way too much and the cake looked like a nucleqr test experiment. It tasted fine, but no one really wanted to eat it.
