Kolak Sweet Soup, Bruguiera gymnnorhiza

Kolak (Avicennia spp. or Brugueira gymnorrhiza)

Kolak is a sweet soup like desert, usually made with cassava or sweet potatoe and cooking bananas.


In this recipe, Avicennia fruits or Brugeira fruits are used instead. This is the famous dish

that is used to break the fast each evening during the month of Ramadan, especially common

in Sumatera.


– 1/4 kg prepared Avicennia fruits. (boiled again after being processed)


– 1/4 kilogram Brugueira gymnorrhiza fruits (boiled)

– 1/4 kg sagu flour

– 1 liter thin coconut milk

– 1 cup thick coconut milk

– two pandan (Pandanus odurus) leaves

– 1/4 kg granualted sugar


If using Avicennia fruits, make sure they are fully processed as instructed on page 8 and use

whole. If using Brugeira fruits, cut into 1 inch pieces. Add fruit to sagu flour and stir.

Boil 1 liter of coconut milk (thin) with sugar. Add pandan leaves after reaching a boil. Add sagu/

fruit mixture and continue to boil until fruits soften. Remove from heat. Add thick coconut milk.

Serve hot or cold.


Tumu is the most widely distributed of the Rhizophoreae family.
The kneed pneumatophores comprise a sponge-like system of air chambers and tubes which acts as an air reservoir when the roots are submerged. The pneumatophores are covered with many lenticels which allow air but not water to enter the root.
Uses as food: Leaves and peeled seedlings are soaked, boiled and eaten. Seedlings are the staple of some in Papua New Guinea, but eaten only in times of famine in Moluccas. Seedlings may be added to betel nut as an astringent. Seedlings are also made into a sweetmeat: they are sliced, soaked to leach out the tannins, then ground into a paste. The bark may be used to flavour fish.
Other uses: The timber is heavy and tough, but has straight fibres and a fine grain. This makes it hard to work with, but valuable as fishing stakes, pilings, telephone poles, railway sleepers, heavy pillars and beams, and other construction. It is commercially planted in Indonesia, Sabah and Sarawak to produce wood chips that is turned into paper pulp or to produce rayon fabric. It is also favoured as firewood and for conversion into charcoal as it produces the most heat among mangrove woods.
Traditional medicinal uses: The bark is astringent and used to treat malaria (Cambodia), cure fish poisoning (Marshall Islands), treat diarrhoea and fever (Indonesia). Elsewhere the fruit is used to treat eye problems, and scrapped skin of the fruit to stop bleeding. The fruit may also be chewed as a betel nut substitute. The leaves are used to control blood pressure (India).
