A beautifully creamy curry, this dish is incredibly easy to prepare. It can be made in advance and left to marinade for a deeper flavour, or eaten immediately if you can't resist the smells eminating from the kitchen! The version below is fairly mild, but if you prefer it a little hotter, just add more chilli to taste. Kafir lime leaves are available from most large supermarkets these days. If you can't get them fresh, you may find them dried, or jarred.
