The Matapi is a long cylindrical basket made from a palm which has a long thin reed like stem called the Mukru. Ground cassava is then placed in this basket and squeezed to remove the poisonous juice.
The Matapi can stretch, so it is hung with it’s ground cassava contents and pulled at, downwards from the lower end. This squeezes out the juices which are collected for the manufacture of Casareep syrup. The rest of the drained cassava is used to make cassava bread.
Matapi is called a Tipiti by the Tupis of Brazil and is made out of the Jacitara palm. In Suriname, it is known as the Carib snake. It has a diamond weave pattern.
The Mukru palm is also used to make the baskets found ubiquitously in the vegetable market.
