Super easy, popsicles can be as simple as juice poured into a mold. Since juice is pricey, I usually use the following ingredients: leftover syrup/fruit juice from home-canned fruit, leftover whey from making yogurt, and any amount of fruits that I have, blended together and frozen for a few hours. I don’t fuss over the measurements for the most part; it’s usually a simple smoothie poured into a mold. Popsicle making is not an exact science. If you do not own popsicle molds, you can usually find them in stores right around now in the northern hemisphere. Amazon has lots of popsicle molds.
