When Europeans first arrived in South America, they gave trees and fruits that resembled their native ones back home the same names. As a result, the Venezuelan Castano was named after the chestnut.
It comes in a football-sized fruit, with a case that divides in three and has scores of nuts inside. These nuts are twice the size of Europan chestnuts, and make a good alternative to them.
