Kefir Gummies
You can buy all sorts of fun silicon molds. I have dinosaurs, flowers, hearts, bows and stars. Silicon is inert and is really easy to clean and the jelly just pops out. I use the same ones for my home-made chocolate and fudge fat bombs!
They are so perfect for lunchboxes. The health benefits of Gelatin are huge combine that with those of Kefir and you are on to a winner!
