Don't let the name fool you, this is not a sweet fishy tea, its just a soup! I always imagined fish tea came out of a need to use a left over commodity.
Just like bread pudding reclaims slate bread, and chicken bones create stock. I
feel that fish heads and other parts were used to make a soup so that they
would not be “wasted” but that’s just my theory. There has never been a thing
wrong with turning trash to treasure. And this soup is quite a treasure.
