The watermelon serves a great base for these berry pops. Make them with the freshest berries you can find. Consider adding a pinch of salt to the blender with the fruit. Like the lime juice, it will really enhance the flavors of the fruit. Make a double or triple batch of these to keep in your freezer. They are a summertime treat adults and kids alike can't resist. Tinker with the recipe if you wish. Try cantaloupe and blueberries, honeydew and raspberries, or Crenshaw melon and strawberries. If you like things spicy and frosty, toss a few fresh jalapeño slices into the blender too for popsicles with added punch.
2½ cup(s), seeded and diced
fresh lime juice
