I'm giving myself a 7. I can come up with recipes off the top of my head, but I'm not exactly Iron Chef material
and I usually start from existing recipes and tweak them. I'm also adventurous and not afraid to try new, difficult recipes from various cuisines. I make a mean Indian curry.
I usually do the cooking, but my husband is a decent cook (otherwise he would have been very hungry in college - the cafeterias suck). I give him a 3 - he can cook a few things well, but nothing fancy. Still, if I come in dead tired after a long day at work, he'll make dinner... he's a good one.
