Fish eyes are weirdly chewy, like those sweets that glue your teeth together. Pretty inoffensive taste, just fishy.The mention of China has reminded me of a fish eye soup I encountered in Hong Kong. A pea-green soup was the final course of a 7-course meal. I was unaware what it contained; until I dipped my spoon into the opaque mixture and an eye bobbed to the surface. Apparently the soup was quite sweet tasting. Suffice to say, I didn't try it.
Century egg.
I'd try most things, but fish eyes and pungent eggs are off my menu.
Generally Chinese food is more flavoursome because everything goes in including all the rich tasty bits and bones. Better to slurp the chicken off the bone than just eat bland white chicken breast meat (which they find baffling).
Century eggs aren't that offensive, but the yolk does turn a weird texture like peanut butter.
Only Chinese food I've really drawn the line at was some fermented fish guts. Just no need for that at all.
