The fruit can grow up to 30 centimetres (12 in) long and 15 centimetres (6 in) in diameter, and typically weighs one to three kilograms (2 to 7 lb). Its shape ranges from oblong to round, the colour of its husk green to brown and its flesh pale-yellow to red, depending on species. The hard outer husk is covered with sharp, prickly thorns, while the edible custard-like flesh within emits the strong, distinctive odor, which is regarded as either fragrant or overpowering and offensive. The taste of the flesh has been described as nutty and sweet.
