Put a baking tray big enough to take the chicken on the hob and over a medium heat. Add the curry paste and cook for a minute until sizzling. Add the coconut milk and stir well to combine. Once the curry sauce starts to bubble, turn the heat off, put the chicken into the sauce and baste the chicken with some of the sauce. Put into the oven for about 1 hour 20 minutes, or until cooked to your liking. You may want to baste once or twice during cooking. After an hour, sprinkle over the breadcrumbs to crisp up.
