Roasted pork with the best crackling and roasted nectarines

1.Dry-roast spices in a frying pan (10-20 seconds). Finely grind with a mortar and pestle, transfer to a bowl and combine with zest, oil and 2 tsp salt flakes. Rub marinade into pork flesh (not the skin) and refrigerate, uncovered, skin-side up to marinate and dry out the skin (overnight). Score skin at 1cm intervals with a very sharp knife (a new Stanley knife blade works well), sprinkle skin liberally with fine salt and tie with kitchen string to secure.

2.Preheat oven to 170°C. Place pork, skin-side up in a roasting pan and roast until skin is crisp and deep golden brown, and the juices just start to run clear when pork is pierced with a sharp knife or skewer (3½-4 hours). Increase oven to 250°C until skin crackles (20-30 minutes). Rest, uncovered, for 30 minutes.

3.Meanwhile, for roasted nectarines, place nectarines on a separate baking tray, scatter with sugar and roast until caramelised (15-20 minutes). Splash with vinegar to taste.

4.Transfer pork to a platter and remove string. Sprinkle with salt flakes and serve with roasted nectarines and their pan juices.
