Preparation time: 10 minutes
Total time: 15 minutes (does not include freezing time)
3 3/4 cups coarsely chopped seedless watermelon
1/4 cup fresh lime juice
1 to 2 tablespoons sugar
1 cup fresh blueberries
In a blender or food processor, puree watermelon, lime juice and sugar to taste until smooth.
Divide blueberries among freezer-pop molds. Top with the watermelon mixture. Insert the sticks and freeze until completely firm, about 6 hours. Dip the molds briefly in hot water before unmolding the pops.
