I love my new ice sphere maker! It makes perfect, clear spheres that last way longer than regular ice cubes. They look classy, too!The spheres are easy to make, but getting the silicon mold out takes a little patience. It needs to be worked up on each side until maybe 1/2" has been exposed, then it can usually be pulled straight up.To make the spheres, simply fill the container with water until it reaches the bottom of a vertical marker on one of the 4 sides of the container. THIS IS IMPORTANT!Next, just fit the three mold pieces together and very slowly push the mold down into the container. As you get closer to the bottom, alternate pushing from one end to the other, doing it just a little bit each time, until the mold is fully seated. You will see a bit of water come up into the 4 holes on the top, and maybe a little water will flow into the grooves on top. That means it is filled correctly. I use water that runs through my fridge filter rather than tap water, just because it filters out chlorine and other contaminants.Here's an important note: You DO NOT WANT TO LEAVE THE CONTAINER IN THE FREEZER TOO LONG BEFORE HARVESTING THE SPHERES! My spheres take about 30 hours to freeze completely with my freezer at just below 0 degrees. I got busy with life and left the container in the freezer for an additional 2 days, and then the bottom part (shown the photo) became completely frozen. If you time it right, only the top surface of the bottom part will be frozen and just running a little warm water will allow you to break through it and pull the ice chunks out (in the picture, it is only partially frozen on top). If you wait too long, that block will be completely frozen (about 3" thick), and if you want to make more ice balls right away, you will waste a lot of water trying to thaw out the bottom ice block. It will not come out easily if frozen down to the bottom.Cleaning the mold is easy, I just rub it under warm water to get any film off. You can knock off the two nubs on the spheres with a butter knife, but I never bother. I highly recommend getting the quad sphere maker, because it's a lot of trouble to make just two. I keep making them and then store them in zip-loc bags in the freezer.If making them on work days, I recommend prepping the container in the evening, putting it in the freezer the next morning, and then harvesting them the day after when you get home from work. Repeat this cycle as needed, and enjoy your favorite whiskey on the rock!
