Pangium edule (Indonesian: keluak or keluwak; Malay: kepayang) is a tall tree native to the mangrove swamps of Southeast Asia (Indonesia, Malaysia and Papua New Guinea[2]). It produces a large poisonous fruit (the "football fruit") which can be made edible by fermentation.

The taxonomy of the tree is uncertain and it may also be classed in the Flacourtiaceae[2] or the Violales.

Ecology and cultivation[edit]

The tree requires many years to mature and the seeds are therefore most frequently harvested from wild trees, as it is not economically feasible to cultivate.[3] Although poisonous to humans, the seeds of the tree form part of the natural diet of the babirusa (Babyroussa babyrussa).[4]

Culinary uses[edit]

Pangium edule seeds used as spice in Indonesian cooking (rawon beef stew)

The fresh fruit and seeds contain hydrogen cyanide and are deadly poisonous if consumed without prior preparation.[5][6][7] The seeds are first boiled and then buried in ash, banana leaves and earth for forty days,[8] during which time, they turn from a creamy white colour to dark brown or black.[9] The method relies on the fact that the hydrogen cyanide released by the boiling and fermentation is water-soluble and easily washed out.

The kernels may be ground up to form a thick black gravy called rawon, popular dishes include nasi rawon, beef stew in keluwek paste,[10] and sambal rawon. A stew made with beef or chicken also exists in East Java.[11] The Toraja dish pammarrasan (black spice with fish or meat, also sometimes with vegetables) uses the black keluak powder.[citation needed] In Singapore and Malaysia, the seeds are best known as an essential ingredient in ayam (chicken) or babi (pork) buah keluak,[12][13] a mainstay of Peranakan cuisine.

Nutrition[edit]

The edible portions of the plant are an excellent source of vitamin C and high in iron.

Synonyms[edit]

  • Indonesian:
    • Keluak,[14] kluwak,[14] kluak,[14] kluwek,[14] keluwek[14] or kloewak (Dutch spelling).[15]
    • Pucung[14] or pucing (Sundanese)[14]
    • Rawan or rawon (adjective referring to food prepared with the seeds of this tree)
  • Malay:
