You have to commend the bravery of whoever first tried these strange-looking fruits. The ackee is sometimes called a "vegetable brain" because only the inner, brain-shaped, yellowish arils are edible. Native to tropical West Africa, this fruit has been imported and cultivated in Jamaica, Haiti and Cuba and is incorporated into some Caribbean cuisine.
Time magazine points out that if improperly eaten, this odd-looking fruit can also make you quite sick. It can cause what is known as Jamaican Vomiting Sickness which, in addition to vomiting, can also lead to coma or death.
