Watermelon-Lime Freeze Pops
Combine all ingredients in the bowl of a food processor or a blender and puree until very smooth and the sugar is completely dissolved.
Divide the fruit puree among 6 or 8 (5-ounce) paper cups. (Alternatively, the mixture may be frozen in ice cube trays or in icepop molds, if available.)
Stand 1 ice-cream stick or plastic spoon in the center of each cup.
Cut 6 pieces of aluminum foil about 4-inches square. Poke a small hole in the center of each foil square and place 1 square over each cup, pushing the stick or spoon handle through the hole to hold it in a straight upright position.
Stand the cups in the freezer and freeze until set, at least 8 hours or overnight. Remove the pops from the freezer and discard the foil squares.
Gently tear the paper cups away from the fruit pops and serve.
