Pangium is a genus in the family Achariaceae containing the sole species Pangium edule, a tall tree native to the mangrove swamps of Southeast Asia (Indonesia and Papua New Guinea[5]). It produces a large poisonous fruit (the "football fruit" or pangi)[6] which can be made edible by fermentation. It is dioecious, with male and female flowers produced on separate individuals.[7]
The taxonomy of the tree is uncertain and it may also be classed in the Flacourtiaceae[5] or the Violales.
Description[edit]
The tree can reach 18 metres (59 feet) in height. The leaves are heart-shaped. The brownish fruit grows in clusters and shaped like a pear.[6]
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.[8] Although poisonous to humans, the seeds of the tree form part of the natural diet of the babirusa (Babyroussa babyrussa).[9]
Uses[edit]
The fresh fruit and seeds contain hydrogen cyanide, thus are deadly poisonous if consumed without prior preparation.[10][11][12] The seeds are first boiled and then buried in ash, banana leaves and earth for forty days,[13] during which time they turn from a creamy white colour to dark brown or black.[14] 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, popular in East and Central Java,[15] and sambal rawon, rawon stew made with beef or chicken, also made in East Java.[16] In West Java and Jakarta, gabus pucung, snakehead fish in pucung paste soup, is a popular traditional dish in Betawi cuisine.[17] 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,[18][19] a mainstay of Peranakan cuisine. The Dusun tribe of Borneo use this pounded kernel as main ingredient for making local signature dish called bosou,[20] a sour fermented fish.
People of the Minahasa tribe in North Sulawesi use the young leaves as a vegetable, slicing them small, then cooking them with herbs and pork fat or meat inside bamboo. Many sellers in the Tomohon traditional market sell the leaves.
Nutrition[edit]
The edible portions of the plant are an excellent source of vitamin C and high in iron.
