Marshmallows (my uncle had a chocolate Lab that he had trained so well he could put a marshmallow on his snout and then tell him “no”. That dog would go cross-eyed staring at that treat on his nose … but he wouldn’t move a muscle until my uncle would say “OK”. The magician who could make anything vanish faster than that dog was able to make that marshmallow disappear has yet to be born!)
I can’t imagine anything I would never eat (including ‘long pig’ after a plane crash), so I can’t add to the list. So just a bit of housekeeping:
Food you will never, ever eat
Balut
Brains
Haggis
BTW - haggis is readily available in the US, it’s just that you can’t import it from the UK. The USDA still has issues with sheep lungs and mad cow disease.
I tried haggis once. I forced myself to swallow one tiny bite, then threw out the rest. Then I tried vegetarian haggis. They somehow managed to make oatmeal taste as disgusting as the real thing.
