Toss cut fruit together in a bowl and then spoon into popsicle molds. Pour enough juice so it comes slightly below each rim. (Pops will expand a little as they freeze.) If you’re using paper cups, cover with aluminum foil (to hold sticks in place). Insert Popsicle sticks. Place on a tray in the freezer for 5 hours or overnight. Run under warm water for a few seconds to release pops from their molds. Enjoy!
