I recently visited Sri Lanka and was taught this by a brilliant Sri Lankan cookery teacher. The pineapple can be substituted for chicken (just add 1/4 pint of water with the coconut milk). If you cannot get hold of indian curry leaves, you can use half the amount of bay leaves. This recipe really is simple but its important to use fresh pineapple as it makes it lovely and sweet. Its best served as a side dish to a more savoury curry.
