Combine all ingredients in a saucepan. If you want to make popsicles, bring the mixture to a boil, turn down the heat and simmer for at least five minutes (this gives the alcohol a chance to burn off). Turn off heat, let the mixture stand for 10 minutes, strain out the solids and pour into popsicle molds. Freeze. If you want to leave the alcohol in and make granitas, don't let the mixture boil. Just summer for a few minutes to let the flavors combine, let it stand, strain and freeze in ramekins.
