I blogged about fruit snacks previously and with some further recipe research I found that fruit juice concentrate works much better than regular juice for making fruit snacks with gelatin. This time I used this recipe: http://www.smartmomstyle.com/all-juice-homemade-fruit-snacks-recipe/. This recipe uses less liquid making for a more dense gummy. I used the same silicon mold and the same brand of grape juice as last time, I just used the frozen concentrate. I did not use any extra sweetener.
The verdict: This recipe was much gummier, less like gelatin, with a much sweeter, juicier taste.
