Absolutely! You can use the tiny paper cups they give you to swish with at the doctor's office, a regular-sized loaf tin, a muffin tin, used yogurt cups, or even an ice cube tray. To center the popsicle stick, cover your container with foil or plastic wrap, then cut a small hole in the center. If you're using a loaf tin, space the sticks at even intervals. Once you unmold it, use a hot knife to cut into individual pieces!
