I've made some pretty spectacular cooking gaffes.
Back in the day, I worked up the courage to invite this girl in my apartment complex over for dinner. For some reason I decided to make enchiladas, which I never made before, and the recipe called for a clove of garlic. I had no idea what a clove of garlic was, so I bought an entire garlic plant (bulb?), took off all the skins, cut the pieces up, and threw it all in.
Few hours later she comes over when the enchiladas are done. Right away she noticed my whole apartment smelled of garlic and said she really liked it. We fixed our plates and sat down to eat. She took a bite, immediately turned white and took off for the bathroom. I thought "Oh crap, that's not good" and took a bite of my own enchilada. Now I absolutely love garlic, but it was so strong it literally took my breath away, like I had been punched in the stomach. It was all I could do not to gag. I started getting embarrased as it was now obvious I made a huge mistake.
She eventually emerged from the bathroom and joked that I was trying to kill her. I lamely apologized that dinner didn't turn out like I planned. We went over the recipe to work out what went wrong and when the part about the garlic and I explained what I did. All I remember is "YOU DID WHAT?????" followed by a stern lecture about how a clove of garlic is one little piece rather than the whole thing. I was really embarrased now and ended up throwing my enchiladas in the trash and ordering a pizza.
Now I know what a clove of garlic is and I'll never forget it.
Another one of my great gaffes- When I was single I would make a huge batch of food on Sundays, like spaghetti or tacos or something, then eat the leftovers for lunch and dinner the following week. One week I decided to make eggrolls so I found a recipe, bought all the ingredients, and spent pretty much an entire Sunday chopping up cabbages, carrots, pork, etc. then assembling and frying about 50 eggrolls. By the way, I wouldn't recommend making your own- way too labor intensive. But that day the deed was done, they tasted good, and everything was great.
Monday rolls around and it's time to heat up some eggrolls for lunch. I put a few in my toaster oven and turned it on. A few minutes later I check on them and MY TOASTER IS ON FIRE!! The flames are going all the way to the ceiling. I guess the oil from frying dripped onto the heating elements and ignited. So I panic, grab a handfull of bath towels, pick up the flaming toaster with the towels, carry it out of the kitchen, through the living room, open the front door, and threw it out my front door as hard as I could. I was on the second floor. The flaming toaster sailed through the air about 50 feet before crashing on the sidewalk below, narrowing missing one of my neighbors, and continued burning on the ground until I found a fire extinguisher and ran downstairs and put it out.
This whole thing took place in about 10 seconds. I've never moved so fast before or since. The next day I noticed there was a trail of holes between the kitchen and the front door where drips of oil had burned through the carpet (lost my security deposit because of it). I'm amazed I didn't burn myself because I wasn't wearing shoes. Lesson learned- eggrolls + toaster oven = BAD!
