Can't help out on the soda jelly, but I have an excellent
recipe for braised Little Debbie cakes with a crushed Cheez-It Gratin topping. I usually serve it with a good can of vintage pull-tab Coca-Cola.
Seriously, if you put me in a room with a 6pk of Dew, the thought of making jelly with it wouldn't have come to me to save my life. I bet this could be marketed for a zillion bucks in the US. Even if they just released it as a fad product, it would make millions!
You could package it in little foil pouches for the Red-Bull skate/snow boarding crowd. I see dollar signs... whats that sound??? *cha-ching... cha-ching*...
