Syzygium samarangense 
The Purple Wax Jambu is a tropical fruit with a striking, deep purple skin and a crisp, watery texture. The flesh is mildly sweet and slightly tart, offering a refreshing bite, similar to an apple or pear. It has a waxy sheen on the skin, which is where it gets its name. Purple Wax Jambu is often enjoyed fresh, in salads, or as a cooling snack in warm climates.
