I’ve eaten some, um, interesting things in my day having traveled to Japan and Ghana.
I mean I had a grasscutter (greater cane rat) stew in Ghana which wasn’t actually bad, if you got beyond the fact you’re essentially eating roadkilled rodent.
In Japan I had a weird gelatin cup with raw octopus and veggies, that was God-awful. One bite and I threw the rest out.
But the one food at the top is Hákarl. I guess it’s fine if you like the taste of ammonia, but I’m not particularly keen on it, so that’s a nope, nope, never again food.
