Kòngròu Bāo (控肉包) is the braised pork belly bun, an alternative name for the Taiwanese folded steamed bun, with the emphasis placed on the kòngròu, the slab of long-braised, fat-rendered pork belly that defines it. Where the common name foregrounds the bun, this one foregrounds the meat, and that framing is the point. The angle is the belly as the load-bearing component: a pillowy, faintly sweet folded bun is built specifically to carry a thick cut of unctuous braised pork, with sharp garnishes added only to keep that richness from going cloying.
The build is a fold rather than a closed bun, and the meat is the work. Pork belly is simmered long and slow in soy, sugar, rice wine, and aromatics until the fat turns translucent and silky and the lean pulls apart under light pressure, then sliced thick. A flat oval of enriched dough, steamed already creased so it opens like a clam, is the vessel; the belly is laid in, then pickled mustard greens for sour and salt, fresh cilantro for a green lift, and a heavy scatter of crushed roasted peanuts, often cut with a little sugar, for crunch and a sweet edge. Good execution shows belly braised far enough that the fat is soft and the meat yields without falling to shreds, a bun steamed soft but holding without tearing, a pickle that is sharp and well drained, and peanut crushed coarse so it crackles rather than going to powder. Sloppy versions fail in clear ways: under-braised belly that chews tough with the fat still solid, too little pickle or peanut so nothing cuts the fat and it sits heavy, a soggy or torn bun that cannot hold the slice, or over-sugared peanut that tips the whole fold toward dessert.
It shifts mostly by the cut and how the fat is balanced against the garnish. The standard build uses belly with its fat intact; leaner or half-fat cuts exist for those who want less richness and are really their own choices driven by that swap. Some stalls add chili or pickled radish, others lean the peanut sweeter. Because kòngròu bāo names the same fold as guà bāo, the canonical treatment of the build lives with that entry; this name is the meat-forward label for it. The lean and half-fat cuts and the dessert-leaning sweet-peanut style each change the read of the fold enough to deserve their own articles rather than being crowded in here. What anchors this entry is the framing it carries: the bun defined by its braised pork belly.
