Star fruit skin is thin, smooth, and waxy with a vibrant yellow-green color. It has a slightly bitter taste and a crisp texture that can range from slightly firm to soft, depending on the ripeness of the fruit.

The skin is often covered in small ridges that run from the tip of the fruit to the center, creating a star-shaped appearance when sliced crosswise. While the skin is technically edible, some people find it tough or sour, so it is often removed before consuming the fruit.

Is it Safe to Eat Star Fruit Skin?
