We finally learned the secret from an unexpected source - the demo video on the William-Sonoma website for using the Zoku Quick Pop Maker! In the video, the demonstrator lets the popsicle just start to set so the outside is frozen but the center is still liquid. She uses a straw to suck out the middle and then refills it with a second popsicle flavor.
The Zoku machine makes this easy since the popsicles set so quickly, but you can certainly use this trick with traditional popsicle molds. Just fill up your molds and let the pops freeze for about 45 minutes. Poke the edges with a toothpick to make sure they’re firm, and then proceed with sucking out the middle and refilling. If you want to keep the liquid instead of having to drink it, you could also use a turkey baster to suck out the middle.
Cream and chocolate also aren’t the only possible fillings, either! We love making double-fruit flavored popsicles or filling the middle with yogurt.
