Star fruit, also known as carambola, can be found in abundance in Southeast Asia where it is heavily cultivated.
The yellow fruit grows on trees in India, Asia, South America, Australia, and the southern United States, but it's enjoyed raw and cooked all over the world. While it's frequently used as a garnish due to its fun shape, it also adds a sweet flavor to a number of dishes like salads and juices.
The carambola plant is believed to be native to Indonesia and flourishes in sunny, humid climates. It is harvested twice a year, typically in late fall and late spring, but can be found year-round. The yellow, oval-shaped fruit has ridges and looks like a star when sliced. Depending on the variety, it can vary slightly in size and color, from light yellow-green to bright yellow. The entire star fruit can be eaten, including the waxy skin, making it easy to prepare and especially good for eating raw and using for decoration.
