Wash pork in salted water, then pat dry with a paper towel.
Light your coals until they become ‘charcoal ready’ – this should take about 20 to 30 minutes.
Mix fish sauce, pepper, soy sauce, caramel sauce, and shallots – coat with pork and leave for 30 minutes or overnight (if you have the time).
Take your pork pieces and lay them on a handheld BBQ grill, so the pork does not stick on the BBQ. If possible, cover the grill with a lid until cooked on each side. Remember to check the pork every couple of minutes and turn it over until the sugar caramelises and the pork is cooked through.
If you are using your stovetop and a saucepan, heat 2 tablespoons of oil until hot. Add pork pieces and cook until the pork caramelises. Top with chillies.
