Chashu Pork (Japanese Rolled Braised Pork Belly for Ramen)
A boneless pork belly slab is rolled, tied with twine, and braised for 90 minutes in soy sauce, mirin, sake, and sugar. Each slice then shows fat and lean spiraled together. Thin slices sold for quick frying cannot be rolled this way, which is why the recipe calls for a whole slab. Those spiral rounds are the familiar ramen topping.
