You’ve probably walked into a cocktail bar at one point of your life and seen some sparkly, crystal ice and wondered “how do they make it so clear”? And no, before you ask, they are not using any special water or magic. A quick google search will actually prove that it is actually very easy to get your ice to be crystal clear. It’s not boiling or purifying the water, but a method called “directional freezing”.
Directional freezing is the process of freezing water in one singular direction, so while the other sides are insulated, the frozen current is working in only one direction and pushes the impurities down. Thicker cut ice also allows for slowing melting, making it less likely to dilute your cocktail, so you can enjoy it for longer! This will give you that beautiful, glass-like ice to add a bit of class to any cocktail.
