What is a carambola fruit?
The carambola (Averrhoa carambola), often called star fruit, is a woody plant in the wood sorrel family (Oxalidaceae) native to tropical Asia. It is distinct from the star apple, a different tropical tree in the sapodilla family.12
The carambola tree produces waxy, yellow-to-orange fruits that are five-angled; when sliced in cross section, they reveal a decorative star shape. The flavor ranges from sharp when unripe to a lightly sweet and sour blend of pear, melon, and gooseberry as it matures.1
