The everyday feast
Rice & curry is a whole conversation.
Steamed rice arrives with several small dishes: vegetable curries, dhal, something leafy, perhaps fish or meat, and a sharp sambol to bring it all into focus. Recipes change from home to home and coast to hills. Ask what is in a dish if you have an allergy or dietary need—ingredients are not always obvious.
Many Sri Lankans eat with the right hand; cutlery is also common, especially in restaurants. Follow your host's lead, and take only what you can enjoy.
