Homemade jello is incredibly easy to make, has ingredients you can feel great about, and with a little "outside the box" thinking, you can still enjoy the convenience of taking it with you--without using plastic.
To make puree, process soft fruit in a high powered blender along with the optional sweetener if you're using that.
2 - 3 tablespoons granulated sugar or honey, 1 cup fruit puree
Measure one cup of puree into a mixing bowl and sprinkle gelatin on top of it.
1 tablespoon gelatin
Bring water to a boil and pour it over the bowl of pureed fruit and gelatin. Whisk until there are no clumps and the gelatin is completely dissolved.
1 cup water
Transfer to desired containers and set in the refrigerator to chill (2-4 hours).
This homemade jello will keep in the fridge for up to a week.
Notes
Any sort of soft fruit will work: Strawberries, Peaches, Blueberries, Watermelon...any fruit that will easily liquefy in a blender is fair game. The images you see here include strawberry, watermelon, and peach gelatin. If you can your own fruit, YES, you can use those. You can also choose your favorite 100% juice and use that in place of the fruit.
Use the off-the-shelf Knox brand gelatin or opt for a higher grade grass-fed gelatin. This is the ingredient that gels the fruit. It is NOT vegetarian. Agar agar is usually used as a gelatin substitute but I haven't tried this recipe using that method. If you do, please chime in and let us know how it goes.
