POPSICLE TIP: Make sure there's an open spot in your freezer where the mold can safely sit and where it won’t tip over. You may have to run the frozen popsicle under the tap for a second to loosen it before popping out and serving. You can also make your own molds by using leftover small yogurt containers or even ice cube trays. Let the mixture freeze a little first before sliding a small stick into the center. It will stand upright better if the mixture is already partially frozen.
