I planted grape vines soon after moving into this house. I thought it would be nice to have grapes for fresh-eating, so most of the grapes are Thompson Seedless. I have a red seedless variety as well.
Guess what? The vines are productive! We have grapes--lots of grapes. Recently a friend told me that she has been freezing her grapes (something I was familiar with) after coating them with Jello powder (a technique I hadn't heard before). She let me try some, and I must admit they were yummy.
Start by gathering your grapes.
Take them off the stems, wash them, and allow to air-dry briefly on towels.
Put grapes into a quart-size freezer bag, filling about 1/3 of the bag. Dump one large box (or two small boxes) of sugar-free Jello mix into the bag. (I imagine you could use the full-sugar variety, and you could probably cover more grapes that way.) Close bag and shake to cover the grapes.
Thanks for fruit--Jello-covered or not!
