If you have never tried Zefir, I would say the closest thing to it are marshmallows. This makes an amazing addition to any party. I love this recipe, using simple ingredients that I always have on hand.
Side note: This zefir may taste different than a store bough, much softer, just because they are fresh.
Note: I would suggest making them late in evening; they take 8 hours to dry so it will be perfect to finish them up in the morning.
