Have you tried mangosteen? It is almost the size of a golf ball. It has thick brownish maroon skin with a broad green brown blemished top. The quick and easy way to eat it is to hold it between your fingers, pinch gently until the outer flesh opens. Inside you can see the white pulp (with occasional seeds) which is the edible part. Simply scoop the fruit using your fingers and savor the delicious tangy taste of this healthy fruit. Yum!
