Peri-peri is Portuguese in origin. It usually consists of crushed chillies, onion, citrus zest and juice, paprika, basil, oregano and tarragon, but I like to add a pinch of ground cumin and ground coriander too.
Tip: If you'd like to concentrate the cooking juices to serve as a sauce, transfer them to a small pot once the pork chops come out of the oven and boil until the liquid has reduced.
