How to Make It
Combine all the peppercorns with the allspice in a spice grinder or a mortar and finely grind them.
Using a soupspoon or melon baller, scoop out the melon flesh without cutting through the rind. Replace the flesh in the melon halves and sprinkle each with about 1/4 teaspoon of the spice mix. Garnish with mint sprigs and serve.
