These ice sphere molds from StyloPhora are super fun! I actually have a set from another company that I never use. I liked the concept but those ones are made of hard plastic, which makes it almost impossible to get the ice spheres out intact.
These new ones are made of soft and flexible silicone. They also come with a handy pop-out funnel and have a printed fill-line so you know exactly how much liquid to use.
After freezing for several hours, I found that the best way to release the ice from the molds is by filling the empty space in the mold to the top with cool water and letting them sit for about a minute. Then the molds popped right off without any trouble.
I think these would be fun to try with fruit juices or with red and blue juice for the Fourth of July!
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
