Red lentils curry is a staple side dish in Sri Lanka. Most of the Sri Lankans will have it for all three meals; with bread for breakfast, with rice for lunch and with string hoppers (steamed noodles with rice flour) or pittu (steamed couscous with rice flour) for dinner. Dhal curry is a versatile dish that can be served with many different main meals.
Sri Lankans call all our side dishes as curries. It could be a stir fry vegetable with grated coconut or yellow curry with coconut milk and turmeric or even a curry with a curry sauce. However here in Western cultures, curry is a term used only for meat or vegetable served in a spicy gravy. However in Sri Lanka any side dish that is served with rice or any main meal is called a curry.
