Carob

The carob (ˈkɛrəb ; Ceratonia siliqua) is a flowering evergreen tree or shrub in the Caesalpinioideae sub-family of the legume family, Fabaceae. It is widely cultivated for its edible fruit pods, and as an ornamental tree in gardens and landscapes. The carob tree is native to the Mediterranean region and the Middle East. Portugal is the largest producer of carob, followed by Italy and Morocco. In the Mediterranean Basin, extended to the southern Atlantic coast of Portugal (i.e. the Algarve region) and the Atlantic northwestern Moroccan coast, carob pods were often used as animal feed and in times of famine, as "the last source of [human] food in hard times". The ripe, dried, and sometimes toasted pod is often ground into carob powder, which was sometimes used as an ersatz cocoa powder, especially in the 1970s natural food movement. The powder and chips can be used as a chocolate alternative in most recipes. The carob tree grows up to tall. The crown is broad and semispherical, supported by a thick trunk with rough brown bark and sturdy branches. Its leaves are long, alternate, pinnate, and may or may not have a terminal leaflet. It is frost-tolerant to roughly . Most carob trees are dioecious and some are hermaphroditic, so strictly male trees do not produce fruit. When the trees blossom in autumn, the flowers are small and numerous, spirally arranged along the inflorescence axis in catkin-like racemes borne on spurs from old wood and even on the trunk (cauliflory); they are pollinated by both wind and insects. The male flowers smell like human semen, an odor that is caused in part by amines. The fruit is a legume (also known commonly, but less accurately, as a pod), that is elongated, compressed, straight, or curved, and thickened at the sutures. The pods take a full year to develop and ripen. When the sweet, ripe pods eventually fall to the ground, they are eaten by various mammals, such as swine, thereby dispersing the hard inner seed in the excrement.
