Heat oven to 200C/180C fan/gas 6. Tear off 4 large pieces of foil, double them up, then place a fish fillet in the middle of each. Spread over the curry paste. Divide the coconut, lime zest and juice, and soy between each fillet. Bring up the sides of the foil, then scrunch the edges and sides together to make 2 sealed parcels.
Put the parcels on a baking tray and bake for 10-15 mins. Tip the rice into a pan with plenty of water, and boil for 12-15 mins or until cooked. Drain well. Serve the fish on the rice, drizzle over the chilli sauce and scatter with sliced chilli. Serve with broccoli and lime wedges.
