re: What's the worst thing you ever cooked?

I've fricked up the rice on a few dishes. Other than that, I don't think I've ever cooked something that I wasn't able to eat.

Swedish Meat(less)ball Stir fry on egg noodles. The dish turned out grey in color and tasted like nothing. Only thing I have ever made where I avoided the leftovers.

Jambalaya... I misjudged liquid one time. Way too soupy. Gave it to the dogs. They said it was excellent.

I was cooking gumbo for the FIL, and I should have known better. I had seen an interesting recipe for gumbo that included basil and mushrooms among other twists, and I thought I'd give it a shot. I get a little bored sometimes cooking the same gumbo over and over, I believe I cook a pretty decent chicken and sausage gumbo FWIW. Well, the FIL basically ridiculed the gumbo from the first bite until he left for the night, he still mentions it from time to time, about 3 years later. The gumbo didn't taste bad per se but it just wasn't traditional gumbo, with the basil flavor.
