Air frying pork loin can yield a succulent roast with perfectly crisp crackling, a much-loved feature of British cuisine. Begin by scoring the skin of the pork loin in a crisscross pattern, taking care not to cut into the meat. This allows the fat beneath the skin to render out during cooking, resulting in a delightful crunch. Generously season the pork with coarse sea salt, ensuring it gets into the scores. Preheat your air fryer to around 200°C (about 390°F), then place the pork loin in the basket, skin side up. Cook for approximately 25 to 30 minutes, checking intermittently to ensure the crackling is achieving that desired golden hue. For an extra boost, you might spritz the skin with a bit of oil halfway through cooking. Once done, let the pork rest for a few minutes before slicing — this will not only enhance the flavour but also allow the juices to redistribute, making every bite tender and juicy. Serve with traditional accompaniments like apple sauce and roast vegetables for a truly British feast.
