Measure your tea into something like a French Press (perfect for loose tea) or a jug or bowl (fine for tea bags) and pour correct ratio of hot water over it.

Allow it to steep for about 4-7 minutes (if using double the amount of tea) OR 10-14 minutes (if using the single amount and wanting to brew it stronger).

While still hot, strain out the tea or remove bags, and then add sweetener to taste (particularly if you're adding honey, you want it to be able to fully melt before the tea cools).

Pour sweetened tea into popsicle molds (if they're plastic, you'll want to let it cool down first).

Stick it in the freezer and wait patiently. :)
