Where does cashew grow?

Cashews come from a tree. They are found inside the stem of a fruit that grows on the tree, called a cashew Apple or, in Portuguese, a cajú . The fruit makes a delicious juice, but the cashew nut is the main commodity. The stem where the cashew nut comes from contains an acid-like oil that must be burned out of the stem, which roasts the nut inside, before the nut can be eaten. This is a very labor-intensive process which explains why cashew nuts are so expensive.
