Brush the watermelon wedges with a mixture of honey, lime juice, and cayenne pepper, then quickly grill them over a very hot fire until grill marks form.
One by one, my friends curiously tried this watermelon and spat out disguised comments like, "weird" or "that's different."
Hmm...not the reaction I was hoping for. But then everyone went back for more, trying to formulate an opinion over this surprisingly odd creation. Sure, it may not be for everyone (best to keep some plain watermelon on stand-by), but it certainly adds some fun when everyone forms an opinion in the great grilled watermelon debate.
In a small bowl, whisk together honey, lime juice, cayenne pepper, and salt.
Light one chimney full of charcoal. When all charcoal is lit and covered with gray ash, pour out and spread the coals evenly over entire surface of coal grate. Set cooking grate in place, cover grill and allow to preheat for 5 minutes. Clean and oil the grilling grate. Brush each side of watermelon slices with spicy lime and honey mixture. Place watermelon and grill and cook until grill marks developed, about 2 minutes per side.
Remove watermelon from grill, sprinkle with mint, and serve.
