Cantaloupe, honeydew, and watermelon give these popsicles their tricolor flair. Puree the fruit with lime juice and condensed milk (or go vegan with a coconut version), then layer into molds and freeze.
In a blender, combine watermelon, 2 tablespoons condensed milk, 2 tablespoons lime juice, and a pinch of salt. Puree until smooth. Taste for sweetness; add more condensed milk as desired. Transfer to a pourable container. Rinse blender; repeat with cantaloupe and honeydew.
Pour 1 to 2 tablespoons of one fruit puree into pop molds. Add 1 to 2 tablespoons each of other two fruit purees and repeat process until molds are filled to 1/4 inch from top. Freeze until firm, at least 8 hours and up to 1 month. To serve, run molds under warm water for a few seconds to release and unmold.
This recipe requires a 10-count ice-pop maker; we like the Norpro 423 (available at amazon.com).
For single-flavor pops, use 4 1/2 cups of one melon variety. For two-flavor, use 2 1/4 cups each of different melons; puree each with half the condensed milk and lime juice and a pinch of salt.
