American Drink: Ice Part 2: How to Make the Best F***ing Ice Ever
3. Boil the water
Totally optional in my opinion. If you want super clear ice, boil it to get rid of trapped gasses. I don’t bother much. I’ve already impressed myself just by getting out of bed in the morning and getting out of my jammies. j/k I’m still in my jammies. If you happen to boil water for French Press coffee in the morning, boil extra but don’t go out of your way for it and again, filtered tap water is just fine.
A particular ice tray is recommend in the post, and I had seen it before, but it (and other new silicone ice trays I’ve seen) suffer from one major flaw: there is no “cheater” slot connecting adjacent cube spaces, which would allow water to move between them and even the levels. This makes it hard to fill with water that’s not straight out of the tap, without spilling; one hand is occupied by pouring, and for most of us that leaves only one hand to hold the tray (if you aren’t named Zaphod Beeblebrox). I’m not sure if this is a design oversight, or a structural limitation imposed by using silicone.
