In order to make a cashew seed edible, it has to be dried & roasted to neutralize its toxic-poisonous shell. The production is very complex. The cashew tree is native to coastal areas of Brazil and introduced into India and some African countries, where they are now also cultivated. Today, the leading commercial producers are India, Brazil and Nigeria, among others, but Brazilians and Indians are the most enthusiastic about transforming cashews into a powerful, healthy, yummy nut. The rest of the fruit is used for beverages and jams, it is very sweet and tasty.
