Crackling is the crisp, blistered skin produced when pork skin is cooked so that surface moisture is removed and the skin puffs and hardens. It is commonly served with roast pork and is prized for its brittle texture and savoury flavour. Successful crackling depends on skin condition, surface dryness, scoring, heat management and the amount of fat beneath the skin.
Pat the skin thoroughly dry and score it with a sharp knife, taking care not to cut deeply into the meat. Scoring helps fat render and gives the skin controlled sections for portioning. Salt is commonly applied to the skin to draw out surface moisture and season it. Some kitchens leave the pork uncovered under refrigeration to dry the skin, following safe raw-pork storage procedures.
Many methods begin with a period of high heat to encourage blistering, followed by a lower temperature to cook the meat through. The exact method depends on the cut and oven. Keep the skin exposed and avoid allowing liquid or steam to soften it. If the meat is cooked before the skin crisps, finish the skin under controlled high heat while protecting the meat from overcooking.
Example: prepare crackling on a pork belly or loin roast by drying and scoring the skin, seasoning it and roasting with suitable heat management.
Wet skin, uneven scoring, excessive steam and insufficient heat can produce rubbery rather than crisp crackling. Scoring too deeply can allow meat juices to escape and soften the skin.
Chef’s tip: keep the skin dry throughout preparation and do not baste it with liquid. Monitor the meat’s internal temperature separately; crisp skin is not evidence that the pork is safely cooked.
