Carob pods grow on the carob tree (Ceratonia siliqua), an attractive evergreen that is found throughout Israel as well as in the rest of the Mediterranean area. The tree reaches a height of up to 9 m (30 ft). The fruit, or pods, measure from 15 to 25 cm (6 to 10 in.) in length and about 2.5 cm (1 in.) in width. As they mature, the green pods turn a purplish-brown color and look like shiny leather. Inside are several pealike seeds separated from one another by a sweet, sticky, edible pulp. Carob pods are widely used till this day as food for horses, cattle, and pigs.
