Did I get this from you? I know it was from someone on this board. If so; thank you! It’s delicious. Try it between two rough-milled oatcakes - nothing finer.
Liver
Chicken buttholes? How many come in a can, like 10,000?
Nava, I wonder what people find so “gross” about rabbit? I guess I could understand if you ate the innards/blood/eyeballs - a lot of people, me included, find that stuff kind of gross, no matter what the animal. But the “regular” meat ie muscle tissue? Is it perhaps the “cute bunny rabbit” factor?
By the way, I remember eating rabbit meat once when I was a kid, and finding it quite tasty.
When I was a child, I was told that everyone hated liver. I think I made up my mind to like it before I ever even tried it.
I’m not usually a fan of mayonnaise, but spread on saltine crackers, it is exquisite. 
I’m was gonna post, “Okra” but that seems pretty mild for this company. 
Brussels sprouts.
Anchovies.
Mmmmm. I love anchovies. When I open a can and only use a couple (added to stew, the glutamate brings out the meaty flavor) I wind up snacking on what is left.
Oprah, on the other hand…
My SIL the Corn Freak makes vanilla ice crea mwith brown sugar and adds cream corn.
It’s not so bad–like eating popcorn washed down with a vanilla milkshake.
Can’t have gumbo without okra 
Also good fried…
My grocery story sells okra chips. All the flavor of okra, plus a salty crunch! They do stick in your teeth though.
That sounds good–I bet it wouldn’t be that difficult to make, either. I do love me some hot pickled okra, too.
Until someone produces actual evidence of large numbers of genuine Scots eating what is verified to be actual haggis I will never believe that “food” to be anything other than the Scottish National Practical Joke On Tourists.
I am convinced that as soon as someone leaves any Scottish pub after eating some haggis the whole place erupts into laughter, people are high-fiving each other and Angus puts another mark on the “gullible foreigners” scoreboard. Then they all go back to eating proper food such as beer.
I don’t think I eat anything that disgusts people but I do eat food so hot it makes even my friends who claim to like spicy dishes say “AAAAAGGGGGHHHH!” I have a pretty high tolerance for heat.
I guess I should clarify…
I was actually looking for weird combinations of foods, like cottage cheese with ketchup or pickle slices spread with jelly (rather than the haggis/liver/testicles fare).
Carry on. 
Pieces of my own skin also.
And scrambled eggs mixed with tuna.
Thousand year old egg is good with gruel. Also, stinky tofu. Spicy soup with pig intestines and pig blood cubes are delicious as well. Sea cucumber too.
I think I’ve eaten most of the gross stuff that’s been listed so far and liked or tolerated most of them. But peanut butter and mayo? That’s just wrong! 
In the spirit of the thread though, putting ketchup on hot dogs would probably qualify. Also, I sometimes crave PB&J with a handful of cornichons on top.
Kippered Snacks with lots of garlic salt
Peanut butter and mayonnaise sandwiches on white bread. Loved them since I was a kid.
**I see that Bosstone has the same affliction. I get the same response in my house when I make them.
Vegemite and Marmite. I’m a born and bred American.
