Carambola [SEP] Introduction
Carambola, also known as star fruit, is the fruit of "Averrhoa carambola", a species of tree native to tropical Southeast Asia. The fruit is commonly consumed throughout Southeast Asia, the South Pacific, Micronesia, parts of East Asia, and the Caribbean. The tree is cultivated throughout tropical areas of the world. The fruit has distinctive ridges running down its sides (usually 5–6). When cut in cross-section, it resembles a star, giving its name as "star fruit". The entire fruit is edible, usually raw, and may be cooked or made into relishes, preserves, garnish, and juices.
