Juicy blackberries, raspberries, plums, and blueberries can be enjoyed even after they've disappeared from summer markets. The fruits are swirled with vanilla yogurt and a shot of lemon or lime juice to form these tart architectural icies.

If you are using individual molds to freeze your pops, place them on a tray to transfer them quickly in and out of the freezer. Loose molds may be inserted into a loaf pan full of beans or rice to hold them still and steady while they are filled and frozen. If pops soften too much during unmolding, refreeze them to harden them up before serving.
