I used to eat these as a child. My favorite was made with plain yogurt mixed with lemonade concentrate.
I used to eat these all the time when I was little, too (which is not surprising, as the recipe was posted by my sister.) I love them. You can kind of suck the juice out of the juice popsicles, and they're not quite as sticky as the commercial cornsyrup kind. The yogurt ones sound weird until you try them, but they are cold and creamy at the same time and so, so good.
Mixed wild cherry juice with cherry yoghurt and had 3 happy little lickers on my hands a couple of hours later. A much healthier (and WAY cheaper) alternative to store-bought icecream cones.
