How to Eat Star Fruit Star fruit, also known as carambola, is a tropical fruit with a unique star-shaped cross-section. To eat star fruit, wash it thoroughly, and slice it into thin slices, as the skin is edible. Enjoy it fresh as a snack, add it to fruit salads, or use it as a garnish for various dishes. Star fruit has a tangy, mildly sweet flavor that pairs well with both sweet and savory recipes. Note that individuals with kidney issues should avoid consuming star fruit due to its oxalic acid content.
