Once cooled, chop up the citrus into bite size pieces and make sure all seeds are removed. Mix together the citrus, thyme, 3 tablespoons honey, and greek yogurt. Taste and add more honey if not sweet enough (or, if too sweet, add a little lemon juice). Divide between your popsicle molds, stick the stick in according to the popsicle molds directions, and stick in the freezer until completely frozen.
