Star Fruit, otherwise known as Carambola, is indigenous to Southeast Asia, but is imported and can be found in US groceries across the country. You’ll likely find them from December to March in the US, though some markets will carry them year round.
High in antioxidants and low in calories, these fruits are known for their dietary fiber. You’ll notice that the outside of the fruit looks waxy, while the inside is soft and juicy. When shopping for Star Fruit, be sure to look for those that are yellow-orange, have little to no dark spots or bruises, and are uniform in size. If you wish to feed right away, avoid the green fruits. However, if you are willing to wait a few days, purchase the green ones and simply keep them on the counter or in a fruit basket for a few days, while they ripen. Once ripe, use immediately, as they over-ripen quickly.
Inside, you will notice small seeds. These seeds are edible and do not need to be removed, though your gliders will likely not eat them. The skin and flesh are both fine to feed, as well, so simply chop and feed and let your littles enjoy!
