I cook-you eat!! Simple--I can't have fish-if it swims I don't eat it-allergies-that being said I will cook it for my DH as it helps his diet. I will have something else. I have lived overseas and have been served weird-to me- foods. I will try them as to not offend my host but that does not mean I like it.
Foods not on my favourite list includes-cabbage, brussel sprouts, any organ meats, cauliflower, blood sausage, some game meat, tofu.
