Otak-Otak is a Southeast Asian snack, usually associated with Indonesia and Malaysia. The main ingredient of the dish is ground fish paste. Ikan tenggiri (wahoo) is most commonly used in Indonesia, while mackerel is the most popular choice in Malaysia.
Also, bandeng (milkfish) and ikan belida (featherback fish) may also be used. In Indonesia, the mixture consists of ground fish, shallots, garlic, scallions, eggs, coconut milk, and either sago or tapioca starch. The Malaysian and Singaporean versions have a distinct orange or brownish color, due to the addition of turmeric, curry powder, or chili.
