Syzygium samarangense is a species of flowering plant in the family Myrtaceae, native to an area that includes the Greater Sunda Islands, Malay Peninsula and the Andaman and Nicobar Islands, but introduced in prehistoric times to a wider area and now widely cultivated in the tropics. Common names in English include wax apple, Java apple, Semarang rose-apple and wax jambu. When ripe, the fruit will puff outwards, with a slight concavity in the middle of the underside of the 'bell'. Healthy wax apples have a light sheen to them. Despite its name, a ripe wax apple only resembles an apple on the outside in color. It does not taste like an apple, and it has neither the fragrance nor the density of an apple. Its flavor is similar to a snow pear, and the liquid-to-flesh ratio of the wax apple is comparable to a watermelon. Unlike either apple or watermelon, the wax apple's flesh has a very loose weave. The very middle holds a seed situated in a sort of cotton-candy-like mesh. This mesh is edible, but flavorless. The color of its juice depends on the cultivar; it may be purple to entirely colorless.
