Place in the freezer for at least 4 hours or overnight.
Rinse the molds for a few seconds under running warm water to loosen the popsicles.
If you are not using a popsicle mold you will need to freeze the popsicles without the sticks for about 30 minutes. After 30 minutes add the popsicle sticks. This will keep the sticks upright in the popsicle as they finish freezing.
