Woku

Woku is an Indonesian type of bumbu found in Manado cuisine of North Sulawesi, Indonesia, which usually used to prepare animal protein sources, e.g. fish and chicken. Woku consists of a ground spice paste made primarily of red ginger, turmeric, candlenut, and red chili pepper, mixed with chopped shallot, scallion, tomato, lemon or citrus leaf, and turmeric leaf, lemon basil leaf, and bruised lemongrass. The dish uses either chicken or fish that is briefly marinated in salt and lime juice before the spice paste is cooked in coconut oil. Once aromatic, the chicken or fish is mixed into the spice paste with water and a pinch of salt until cooked. Woku is an authentic Manado sauce that gets its name from daun woka, a kind of young coconut leaf that is usually used as a rice wrapper. Originally, the initial woku dishes were all wrapped in young coconut or banana leaves before being cooked, much like how pepes or ketupat are cooked.
