The use of spices in Sri Lankan cuisine differentiates it from Indian, Thai, Maldivian and other regional cooking styles as there's little use for curry pastes. Some of the most essential ingredients for a savoury dish or curry in Sri Lankan cuisine include turmeric, chilli powder, pepper and roasted curry powder. Spices such as cumin and coriander are used sparingly if at all in local dishes, which also sometimes call for chilli pieces, gamboges and mustard seeds. The freshness of the spices as well as how it is stored also impacts the overall taste of local meals and dishes so it is crucial to use air-tight containers to store spices.
