Let’s talk about how these melt.
Instead of melting and dripping down the stick like a store bought popsicle does these just gel up into a Jell-O consistency. Of course if you have messy kids like I do they won’t be 100% mess free. The picture above shows two popsicles that had been sitting on the plate for about 10 minutes out on a very sunny and hot Florida day (it was in the high 80s). The one on the right shows how it held its shape and the one on the left was picked up and eaten. When they melt it is like eating really cold Jell-O… on a stick.
The picture below was what the popsicles looked like after being out on the plate for about 20 minutes. Underneath the popsicle there was wetness which seemed to be mostly condensation since it was clear. There may have been a few drops of melted popsicle.
Okay now for the ‘why do you need the extra sugar question‘
The answer is that you don’t need to add sugar because the Jell-O mix has sugar in it BUT if you don’t add the sugar the popsicles don’t freeze as well. When you try to pull the popsicles out from the mold the stick tends to come out leaving the popsicle behind. Who wants a popsicle without a stick… that isn’t any fun! If you don’t want to add the extra sugar then I suggest using plastic cups or ice trays for your mold so you can get them to come out without loosing the stick. If you are using a deep mold then I would add the extra sugar. (Trust me I have tested this. We would up only being able to get 2 out of 10 popsicles out with their sticks still intact. I had to use a knife to get the others out.)
Here is a good picture that shows the ‘gel’ factor. This popsicle was one from the plate after sitting for the 20 minutes. Notice the transparent layer along the bottom? Take one lick and that layer is all yummy Jell-O.
