My step-mom and dad split up the cooking (until they divorced). The things my dad made were usually pretty good ... same for my step-mom.
My wife doesn't like to cook main-course stuff (she can bake her ass off though). I usually do the cooking. I've worked in kitchens several times during my life and have more than a few recipes from a couple of really good chefs.
My daughter prefers my cooking to almost anyone else's (except her uncle who is a chef). She has even thrown a fit when mom was going to cook some scrambled eggs for her rather than me.
