I had a whole whack of strawberries and watermelon that needed to be used ASAP and it was supposed to be super hot out. Perfect time to make popsicles!! My mother in law was over when I was making them and she told me they used to add jello powder to their popsicle mix when the kids were little. Brilliant!! The jello powder essentially becomes a glue that holds the popsicles together instead of melting into a sticky mess. Of course, the popsicles melt eventually but my kids ate them in the blistering heat and they actually held together for a while!! I was so impressed!!
