I tend to be fairly pragmatic with issues like this. For instance: I haven't had liver & onions in about 35 years, but I'd scarf-down a big pile of it after going without food for even one day. (CAUTION! some forms of liver you might be tempted to try in a wilderness situation, mostly carnivore like sled-dog or Polar Bear, have toxic levels of vitamin A, drive you blind & maybe kill you dead) Fried Okra: I might last a day or two before eating any. Foods I haven't tried that might take a week or more of going hungry; Balut: Sounds revolting. But hunger is the best sauce, right? Speaking of sauce, how about Nuoc Mam? "If you can get past the smell, it's pretty good." I've heard that one for Kimchi, too but the 'wall of smell' factor seems to be an order of magnitude higher with Nuoc Mam.
