Some rare fruit names include ackee, rambutan, physalis and the African horned cucumber. Ackee is native to West Africa, and is imported and cultivated in Jamaica, where it is the national fruit. If eaten improperly, ackee can cause an illness in which vomiting can lead to coma or death.
Unripe ackee contains a poison called hypoglycin. The fruit’s protective pod must be red before opening. The only edible portion inside is the yellow flesh that surrounds toxic black seeds.
Rambutan has a hairy exterior that when peeled away reveals a tender fleshy fruit. Its taste is a combination of sweet and sour, much like a grape. It originates in Southeast Asia, but is imported throughout the world and is commonly cultivated in Hawaii.
Physalis has a lantern-shaped husk that is pale yellow and green in color. It is a member of the nightshade family and has a taste similar to a tomato. It is typically imported from South America.
The African horned cucumber has a spiky yellow exterior that houses a juicy green interior. Its taste is said to be a cross between a zucchini and a cucumber. It is rich in vitamin C.
