George Carlin had a bit about the fact that there is no blue food. There's a reason for that - as evidenced by this particular Frankenfood. I admit to having wondered what it was like, and bought a box a couple of months ago without knowing if it qualified under the "any jello but red" colonoscopy prep rule. When I checked with the nurse, she said not to have it. So I didn't get to making it until the other day. The picture on the box has raspberry and blueberry but the only flavor came from the fresh blueberries I added to the mold. Otherwise, this aquamarine-colored food-like substance has a strongly perfumy smell but no identifiable flavor other than sweetness. In comparison, the other Jell-O flavors are like eating just-picked local fruit! If I ever want to make blue jello - like for a flag-theme dessert - I will buy white grape juice, plain gelatin packets, and blue food coloring.
