Place some of the orange juice and sugar in saucepan and cook for approx. 5 min. over medium-low heat until the sugar has completely dissolved. Add lemon juice and remove from heat.
Add the remaining orange juice to measuring cup along with the sugar-juice mixture and stir. Divide evenly between popsicle molds and insert popsicle sticks. Transfer to freezer for approx. 6 hrs. Enjoy!
