Use a sharp knife and cutting board to cut the watermelon into 1-inch thick slices. Then, slice each round into 3-4 evenly sized fries, resembling thick French fries. Place the cut watermelon on a platter and refrigerate for 10 minutes to chill.
In a small mixing bowl, combine coconut milk, lime juice, honey, and lime zest. Whisk until smooth and well combined. The dip should be slightly thick with a glossy appearance. Taste and adjust sweetness if needed. Chill the dip in the refrigerator while preparing the watermelon.
Arrange the chilled watermelon fries on a serving platter. Drizzle the coconut lime dip over or serve on the side for dipping. Optionally, garnish with additional lime zest or shredded coconut for presentation.
Serve immediately for the best crunch and juiciness, allowing diners to dip or enjoy the watermelon fries as desired. The natural texture of the watermelon should remain crisp, contrasting with the creamy, tangy dip.
