Cut open a Fuzhou fish ball and the first surprise is its structure. The pale outside can enclose a savoury pork filling. Fish has become the wrapper rather than the centre, reversing the arrangement familiar from many dumplings.
The city’s official culinary register describes fish flesh worked into a paste with salt and water, then combined with sweet-potato starch. The mixture must become cohesive enough to close around a small portion of filling. It is shaped into a ball and cooked carefully before being served in broth. The rounded surface conceals several distinct tasks: removing bones, working the paste, balancing its consistency and sealing the filling. The desired springiness is made through those actions. It is not simply a property that a piece of fish possesses before it reaches the cook.
