I've made a similar recipe several times including for wedding take-away gifts for guests in adorable 4 ounce jars. I use 12 cups rhubarb with 2 cups sugar (if you've got good strawberries its plenty sweet). Let stand overnight and then add 6 cups strawberries. Boil approx 5-8 minutes and stir in large package strawberry jello. Proceed with hot bath for long term storing.
