I’m aware of a few different ways to make perfectly clear ice, but each has its own tradeoffs.
I’m also aware of a whole bunch of different ways people claim to be able to make clear ice, but I’ve been unable to replicate.
What are you doing? Does it require special equipment? Do you recommend it?
I just use those free marketing tumblers they hand out for you to put your coffee in. Or go to a thrift store and buy more for $1 a piece.
Fill it up, put in the freezer, come back in a few hours and pour some water on it if it’s not popping out on its own. Double bag them in the freezer.
If you forget about it it’s fine you just need to break off the bottom not clear part after and check that it didn’t break the tumbler.
You don’t have to worry about them much and they fit basically anywhere and if it breaks it’s cheap enough to replace but is unlikely as it doesn’t expand that much.
Plus the pucks are easier to work with than the big blocks made by using a cooler and take up way less space in the freezer too.
Works well for me and I wouldnt do anything else.
