Hi SFA, as it happens I have 100 Solo cups 5.5 oz, and I fill them with Jell-O made with fruit juice and fruit such as strawberries. raspberries, pineapple, peaches or fruit cocktail. I also add in some cream cheese or cottage cheese, whiz in the blender, and freeze the little cups.
They are better for you than ice cream probably, and taste SO good...like sherbet...I keep 'em for snacks sometimes even breakfast!
