01 - In a large mixing bowl, combine the Greek yogurt, fresh lemon juice, lemon zest, honey, vanilla extract, and sea salt. Whisk thoroughly until the mixture is smooth and uniformly blended.
02 - Gently fold in any desired optional ingredients such as chopped fresh mint or mini white chocolate chips, distributing them evenly throughout the mixture.
03 - Pour the yogurt mixture evenly into popsicle molds, tapping the molds lightly on the counter to release any trapped air bubbles. Insert popsicle sticks into the center of each mold.
04 - Transfer the filled molds to the freezer and freeze for a minimum of 4 hours, or until the popsicles are completely firm and set.
05 - To release the popsicles, briefly run the outside of each mold under warm water for a few seconds, then gently pull the popsicle upward by the stick. Serve immediately.
