Introduction to Cashews

Cashews grow in tropical locations around the world like India, Vietnam, Ivory Coast, and Sri Lanka. The tree belongs to the same family as poison ivy and cashew plants contain a toxin called urushiol. The toxin is found in the plant itself and the brown oil inside the nut’s shell. It can cause burns, itches, and blisters. Therefore, unprocessed cashews are considered dangerous to eat or even touch. This is also why they require more rigorous processing than any other nuts.

Many people think that cashew products selling on the market is as raw as they are from the tree. In fact, every single cashew went through a very complex process before they reach consumers and consider as edible.

Each cashews fruit bears only one shelled nut (drupe), hanging at the bottom of each fruit. Workers have to separate the drupe from the cashews fruit by hand. The nuts must then dry under the sun to draw out caustic liquid from the shell. The most dangerous and critical step is to split open the nut since toxic oil coats the drupes. Factories used to do this step manually by hand because cashews are brittle to avoid machines breaking the nuts. Todays, advance technology helps machine to crack the shells while keeping most of the nuts intact and helps to minimize risks to workers. Not only that, even the following steps in the process will highly depending on workers, who have to do them by hand. The nuts are roasted to ensure the toxic substance inside is destroyed. Workers will need to peel off the husk and the dry outer covering that covers each nut because it is high in tannins and could irritate one’s throat. Removing the outer covering of each nut requires skills and practice. This step is the most difficult and has the most impact on price of cashews.

The truly raw cashews are still in their shell (drupe), which are not edible. Even raw cashews sold in the market have been carefully harvested and slightly roasted to remove the toxic oil in the nuts. In general, raw cashew nuts sold in the market have been processed and slightly roasted.
