re: The Best Dish You've Ever Cooked

I don't really cook anything too fancy but a few things that I think I cook well would include

Veal Marsala
Osso Bucco
Steaks
Butternut Squash Soup
Sometimes I'll get lucky and make a good curry
Palak Murgh

I'm getting pretty good with gumbo and some other soups/stews but that's all easy.

If it involves any sort of really high level techniques I'm going to screw it up.

I'm good at combining flavors, not so much with technique
