A bit late in the season for this where I live, but for an easy and fairly healthy frozen treat, try this: Remove 16-24 ounces seedless grapes from their stems, rinse them, and put them, still wet, into a baggie or freezer container. Add a 4-serving packet of flavored gelatin (regular or sugar-free), seal, shake to evenly coat the grapes, and freeze. They can be eaten while completely frozen, but I prefer leaving them out for a few minutes, until frost appears on the skin, because IMO there’s more flavor when they are slightly thawed. Use whatever flavor gelatin you like.
Does this work for any fruit or only soft texture fruits like grapes?
Beats me but I think it requires bite-sized pieces, with the skin helping to keep the pieces intact. Chocolate-dipped frozen banana slices are great; could work.
