Usually, goby, snakehead or catfish is used; however, they are also sometimes substituted with cod, snapper, barramundi, salmon, whiting, or perch. The fish fillets are rubbed with or marinated in a freshly-made yellow or green kroeung[2] mixed with coconut cream or coconut milk and eggs. The curry mixture is placed in a banana leaf container with great morinda leaves at the bottom and steamed for around 20 to 30 minutes until the curry achieves a mousse-like consistency.[2] Great morinda leaves can also be substituted with Swiss chard leaves if not available.[5]
Fish amok is served hot usually in either banana leaf containers or coconut shells and eaten with steamed rice.[2]
Many restaurants in Cambodia also serve less traditional versions of amok with chicken, tofu, or beef instead of fish. Other deviations include the use of a store-bought herb paste, other types of kroeung, more liquid consistency and cooking instead of steaming.[6]

If the description of fish amok sounds like Thai cuisine (arguably the most popular Southeast Asian cuisine in the world), that's because many elements of today's Thai cooking was influenced by Khmer cooking techniques and principles perfected over centuries.. (...) A dish that exemplifies Khmer influence, is fish amok, a steamed snakehead fish curry that is redolent of lemongrass, galangal and coconut aromas.

The origins of fish amok are a source of regional debate. Dishes of this kind aren't unique to Cambodia. Malaysia and Indonesia boast the similar otak otak and Thailand cooks a spicier hor mok but neither nation embraces them with the passion of Cambodia. "Amok" in the Cambodian language, Khmer, only refers to the dish whereas in Thai, "hor mok" translates as "bury wrap," suggesting amok may have come from Cambodia's neighbor.
