Griddling aubergine slices, then spreading them
with tomato sauce, scattering over mozzarella
and grilling until melted.
Heat oven to 200C/fan 180C/gas 6. Heat 2 tbsp of the oil in an ovenproof sauté pan and brown the meat well (you may have to do this in batches), then scoop out of the pan. Add the rest of the oil and the aubergine, brown on all sides, scoop out and add to the pork. Tip the sugar into the pan and leave to caramelise slightly, then return the pork and aubergine to the pan with the star anise and cinnamon, then coat in the sticky caramel.
Add the onions, ginger and half the chilli, and cook for a few mins with the pork. Add the coriander stalks and splash in the fish sauce and enough water to come about a third of the way up. Cover and place the dish, undisturbed, in the oven for 1 hr, then remove from the oven and add the lime juice and more fish sauce to taste. Stir through half the coriander leaves and the remaining chilli, and scatter over the rest of the coriander. You should have a hotpot of tender meat with soft aubergines all in a punchy little sauce.
