The rib section, where lean and fat stack in alternating layers to give the cut its striped cross-section. The thick fat layers turn richly sweet when cooked, and the lean layers keep that richness in check. Left bone-in and trimmed into a rack, this same cut goes by a different name: spare ribs. How thick those layers run differs between the rib side and the belly side, so the fat-to-lean ratio shifts depending on exactly where a piece is cut. The fat itself runs a milky white, making for a strikingly layered cross-section against the lean.

It's the standard base for kakuni (braised pork belly) and bacon, and long, slow cooking melts the fat and lets the lean pull apart tender. Left skin-on, it's often parboiled first to render off excess fat, and with such thick fat layers, judging the heat carefully — avoiding both undercooking and toughening it — matters. Cooking it whole before slicing is said to give a cleaner look at those layers once plated. A pressure cooker can shorten the braising time while still getting close to that same melting texture.

It became the go-to ingredient for dishes built around slowly taming fat, like kakuni and bacon, precisely because its layered structure rewards long, gentle heat more than almost any other cut. Left on the bone as spare ribs, it's the same cut wearing a different face. That its richness has always been treated as the point, not a flaw, says something about its whole culinary role.
