What Is Star Fruit?
Star fruit is an exotic variety of fruit that is packed with nutrients and minerals, which has recently gained global popularity. Starfruit is the fruit of a tree with the scientific name Averrhoa carambola. The fruit is approximately 3-6 inches in length and the flesh of the fruit is greenish yellow to yellow and is crisp and tart in taste. It may also have two to five tiny, edible seeds. The name comes from the distinct shape of this fruit when it is cut in a cross-section – it has the shape of a star. The entire fruit can be eaten including the waxy outer layer. The tree of this fruit can be found throughout Southeast Asia and other tropical areas including the Caribbean and Latin America.
When the fruit is ripe, it is light yellow with slightly brown ridges. It is best to avoid smaller, green fruits as these tend to be quite sour and unpleasant to eat. This fruit is sought after due to its nutrient density and antioxidant levels.
