When is a watermelon not a watermelon? When it's a refreshing frozen confection combining tangy raspberry sorbet, sweet honeydew, and chocolaty chips.
Halve the honeydew, discard the seeds, and chill it overnight in the fridge.
The next day, put the halves in the freezer for 15 minutes, pull them out, and pack them with sorbet, gently evening off the top.
Using a chilled knife, slice each half into halves again (make sure the melon is sorbet side up).
Finally, insert a row of chocolate chip seeds and serve immediately.
