Let's get the obvious out of the way first. You can't go to Sri Lanka and not have an authentic Sri Lankan rice and curry. Unlike Indian curries, Sri Lankan curries are more heavily spiced, and coconut milk and flesh is used in abundance. A typical plate of rice and curry will include a generous serving of rice, a minimum of four vegetable curries, a type of protein - usually fish, chicken or even soya meat, and a mallung (finely chopped salad). Accompaniments will include deep fried red chilles, pappadams, and various sambals.
