Do you know spicy lime pickle? It is one of authentic SriLankan foods. I heard SriLankan people eat it with rice and curry. It is made from lime, salt and chili (sometimes turmeric,too). We made it with sushi and it suits to sushi very much more than we have expected! Though it is spicy a little bit, it is a good accent and a good combination of Srilankan foods and Japanese foods! You would not be able to eat this menu other than here all over the world! And it is one of popular menu among the vegetarian.
