Pork fat does the structural heavy lifting in this formulation, specifically requiring a thirty percent fat ratio to prevent the finished spheres from turning dry and mealy. Ground meat must be chilled until half-frozen before mixing to keep the animal fats solid, which prevents the proteins from melting prematurely under mechanical friction. Dried shiitake mushrooms introduce concentrated glutamates that fresh caps simply cannot match, trading moisture for an intense umami density. Rehydrating these mushrooms requires one to two hours of soaking time, followed by thorough manual wringing to ensure excess water does not dilute the meat paste.
Achieving the characteristic bounce of these meatballs relies on physical protein extraction rather than chemical leavening alone. Beating the mixture with a flat beater at medium speed for ten to fifteen minutes shreds the muscle fibers and forms a sticky, cohesive paste. Crushed ice added directly to the bowl moderates frictional heat generated by the mixer, keeping the temperature low enough to preserve the gelation properties of the meat. Simmering water—never a rolling boil—prevents the newly formed proteins from seizing and cracking during the final cooking stage, which maintains structural integrity as the meatballs rise to the surface.
