It was a choice between jam and gelèe pops, watermelon and musk melon. I chose watermelon gelèe. After an excellent experience with jam (a grape one), jelly seemed easier. After all, all the work is being done by the gelatine. My version gets a little runny after about five minutes out of the refrigerator, since the amount of fruit jam used was almost miserly. But its more of a grab-spoon-scrape-tin-and-pop-in-mouth-version.
