My DH's Grampa's "Borscht". Oatmeal, pickled beets, milk, and sometimes if he wanted it extra special some pickles. Served with bacon and eggs. He delighted in offering it to the grandkids!
His own worst experience as a child was "sucker fish patties." Growing up poor, his mom was good at canning, and very thrifty. A nearby walleye hatchery was giving away suckers by the gunnysack, so she and my mom went up there and brought back a trunkfull of suckers. After canning them all, the only recipe they ever used them in was "sucker patties." They would drain all the fluid out of them, add some onion, press them into patties, squeeze as much fluid out as possible, then fry them until all remaining moisture departed. The kids would drown them in Ketchup, but they were still awful. Made even more so by his dad pontificating about how great they tasted!
As an adult, my DH was on a hunting trip and ran out of food. Spurred by hunger and a conversation with a person he had talked to who believed a person should only kill an animal that they eat (he traps furbearers and had a job trapping problem animals, as well), he decided to eat fox for dinner. He had shot and skinned a fox earlier that morning, and flung the carcass into the bushes. Returning to camp after an unsuccessful day hunting, hunger gnawing at his belly, he retrieved the fox and looked it over. It was very dark, rich, fatty looking meat, leaving his hands greasy from handling it. He removed the backstrap, which is the New York if its beef. It still smelled pretty much like the fox skin, so he decided to boil instead of frying it, hoping to boil off any off flavor. He boiled it twice, throwing out the first pan of water. He dumped a bunch of Mrs. Dash into it, then stabbed a fork into the first chunk. It was very tender, well seasoned, and tasted EXACTLY like the foxes musk glands. (Think skunk on a smaller, sweeter scale.) As hungry as he was, he choked it down, and managed a second bite. Stomach rolling and twisting now, he threw out the rest. Strangely enough, he had no more desire for food.
