Then, the nuts are to be collected in a bucket before hulling them. The most difficult stage of harvesting is to crack open the husks. One must never try cracking the husks with their teeth. A hammer can be used to crack open the hull and extract the nut. Thereafter, the shells covering the nuts are washed and it is essential to wear gloves while washing the shells as they too have a potent stain.
