Pork Belly

Belly is built in sheets. Because it holds nothing up, the pig lays it down as alternating bands of fat and lean rather than as one worked muscle with marbling threaded through it. That structure explains both outcomes: a thin slice crisps into something rigid, and a thick slab roasts into a crackling lid over a soft, nearly custardy middle. Same anatomy, two entirely different results, decided by how it is cut.

Cure, then smoke, in that order. Salt draws water out and firms the meat. Nitrite fixes the pink colour, slows the fat from going rancid, and is responsible for most of what people recognise as the cured flavour — the smoke is the accent, not the substance. That is the whole distance between what is sold fresh and what is sold sliced in a packet.

"Uncured" on a label does not mean no nitrite. Those products are cured with celery powder or celery juice, a concentrated nitrate source that converts to nitrite in the meat exactly as the purified curing salt does. The USDA simply does not permit the word "cured" unless the nitrite was added as a curing salt, so the label says one thing and the chemistry says another. If you are avoiding nitrite, this is not the way to do it.

The same cut has other names, and one famous name is a different cut. Pancetta is this slab, salt-cured and usually rolled, not smoked. Chinese and Korean cooking use it fresh, braised or grilled over fire. British and Irish back bacon, though, is not belly at all — it comes from the loin, which is why a rasher is mostly lean with a rind of fat down one edge instead of striped all the way through.

Two stages or nothing. Fresh belly wants a long, gentle cook to render the fat and soften the lean — a couple of hours somewhere around 300°F — followed by a short, hard, dry blast to blister the skin. Going straight to high heat gives you a leathery top over unrendered fat. For crackling the skin has to be dry: score it down to the fat but not into the meat, salt it, and leave it uncovered in the fridge overnight.

Honest cost note. It is cheap per pound, but a large share of that weight renders away in the pan. Judge it by what reaches the plate and it is closer to mid-priced than the sticker suggests.
