Spiced tuna and sticky rice in banana leaf

This is a fishy version of lemper ayam, a popular street food in Indonesia made using shredded, cooked chicken, which you can use in this recipe instead of the tuna. The tomato side dish is a salady spin on sambal colo colo, a traditional tomato-based garnish for grilled fish from Maluku, and it makes an excellent, though not essential, accompaniment. Candlenuts, fresh galangal, kaffir lime leaves and banana leaves can all be found at Thai or Vietnamese food stores.
