   1      medium        watermelon
   1      cup           mascarpone cheese
   1                    orange -- zested, segmented, juices set aside
   2                    lemons -- zested, segmented, juices set aside
   1                    grapefruit -- zested, segmented, juices set aside
   2      tablespoons   sugar

Preparation:

Cut watermelon in half lengthwise. Using a melon baller, cut into balls and place in a shallow serving bowl. In a blender, mix the mascarpone and the citrus fruit juices and the sugar until smooth. If too thick, thin with a little water (it should be as thick as yogurt). Drizzle the mascarpone over the watermelon balls and sprinkle the fruit segments over and serve cool.
