Any combination of summer or tropical fruits is delicious in this sweet, gingery salad. Serve it in individual bowls or goblets if you don't want to use split coconuts. Pick coconuts that are free of moisture around the "eyes." They should be heavy with liquid -- you can hear it when you shake the fruit.
For a dessert you can serve in "fruitful" bowls, fill hollowed-out watermelon halves with slices of papaya, honeydew, and cantaloupe, as well as balls of the watermelon -- all sprinkled with lime zest.
