Jengkol' is common name of the tree Archidendron pauciflorum (also known as Pithecellobium jiringa, Pithecellobium lobatum and Archidendron jiringa), native to Southeast Asia. Its beans are a popular food in Indonesia, and are also consumed in Malaysia (where they are known as jering), Myanmar (where they are called Da Nging Tee or ngapi nut, named for their odour, which is similar to that of ngapi (shrimp paste)) and in Southern Thailand, where it is called Luk-nieng. [http://www.sos-arsenic.net/english/homegarden/possi_dev.html] The large brown legumes are very popular and cooked as satay or curry, especially rendang, in Indonesia.

The beans are mildly toxic, due to their unique djenkolic acid content, a protein amino acid, which causes djenkolism (jengkol bean poisoning).
