The interior flesh is mild tasting, somewhat like a melon and is the edible part of the fruit.
Look for healthy looking fruit that has bright even colored skin. Some speckling on the skin is acceptable, but too much speckling indicates that the fruit is overripe. If the "leaves" are brown or the stump is brittle, the fruit is overripe. To tell if it is ripe, hold the fruit and gently press the skin with your finger. It should have a very slight give, like ripe kiwi. When it has that give, it's time to prepare it. If it's hard, let it sit on the counter for a few days to ripen. You don't want it to be mushy.
With a large spoon, scoop out the white flesh.
Slice the flesh and eat plain or in fruit salad. The flesh can be pureed in a blender and used in drinks.
