A dish of Kelantan and the north-east coast. The blue comes from butterfly pea flowers boiled with the rice; kerabu means a salad of raw herbs and vegetables, and the rice comes heaped with them, sliced as fine as thread.
It's eaten with grilled or fried fish or ayam percik (spiced grilled chicken), salted egg, fish crackers, and budu — Kelantan's fermented anchovy sauce.
