Plantain is the big brother of the sweeter banana. Commonly in Spain it is grown in the Canary islands, or imported from Columbia (or elsewhere). Plantain in Spain is sold either as "Platano Macho" or "Platano Verde", actually the same thing, but the former is sold ripened, the latter needing to be cooked to be served. Plantain is more popular amongst the immigrant latin population in Spain, possibly it wasn't even grown (in the Canaries) or sold here more than 10 years ago. Plantain despite being exotic is even more common in England through immigrant population coming from either West Indies or West Africa.
