Use Hot Water To Make Crystal Clear Ice Cubes
Ice made from cold water looks cloudy because air that is trapped in the water become suspended in the ice. If you boil water before pouring it in the ice cube trays, you release most or all of the air that would otherwise be trapped in the water — making the ice cubes crystal clear.
Crystal clear ice cubes look great when used with designer ice cube trays. For any holiday or event, designer ice cubes are a cool thing to entertain guests and spark conversation.
Ikea has a few designer ice cube trays that you can pickup or Amazon has hundreds available for delivery, including: Christmas Trees and Snowmen, Penguins, Ice Invaders, Peace Signs, Hearts, Homer Simpson, Stewie (Family Guy), Stars, Skull and Crossbones, Butterflies, Dinosaurs …etc. They even have molds to make Shot Glasses and Stir Sticks out of ice.
Another secret: the ice cube trays can also be used as Jello molds!
Remember, you’ll have to boil water to make it hot because you can’t use hot water from the tap – explained here.
