Sometimes when seafood has fermented or not been salted at all, in street food, it tastes sweet. It shouldn’t, because usually fermented fish tastes bitter, but after a while, it begins to taste sweet.
Why? What’s the chemical change that makes this happen?
Lots of very northern fermentation methods make it taste this way, but why?
Is that because it’s starting to turn by then, or some other change? I know some chemicals change kinda quickly. Do some acids start turning into sugars, or do the fish wind up frozen or being marinated or injected something?
Thank you for answering!
