Make your simple syrup by combining your honey and water in a medium saucepan over medium heat. Once the honey is dissolved remove from the heat and let cool. Once cooled add your fresh grapefruit and lemon juice and mix well. Pour your mixture into popsicle molds making sure to not over fill. Add 2-3 sprigs of basil to each mold and cover and freeze for 24 hours. Remove your popsicles from their molds based on the manufacturers instructions and enjoy!
