From both sites it states that Tutuoyu Geng is a popular Taiwanese street food where crispy battered fish that was prepared separately is served in a thick soup which has a salty, sour and sweet flavour with hints of smoky fish. Crispy batter is not really hard to make as we can use any deep fried battered fish on this one.
