Carambola, commonly referred to as starfruit, is the fruit of Averrhoa carambola. The fruit has distinctive ridges running down its sides (usually five but can sometimes vary); in cross-section, it resembles a star, hence its name.
The entire fruit is edible, including the slightly waxy skin. The flesh is crunchy, firm, and extremely juicy. It does not contain fibers and has a texture similar in consistency to that of grapes.
Starfurit’s are best consumed shortly after they ripen, when they are yellow with a light shade of green or just after all traces of green have disappeared. They will also have brown ridges at the edges and feel firm. Overripe Starfruit will be yellow with brown spots and can become blander in taste and soggier in consistency.
Starfruit is rich in antioxidants, potassium, and vitamin C; and low in sugar, sodium, and acid. It is also a potent source of antioxidants.
