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?
For the vacuum pressure pulling, are you doing that in a chamber sealer then freezing the bag?
Yeah I tried it by putting the ice trays directly in the chamber sealer, and then vacuuming it until a bunch of air bubbles out, even to the point of getting it boiling sometimes. Then I’d try to gently transfer it to the freezer. And then get cloudy ice anyway.
I don’t think I’d be able to do it sealed in a bag, because the shape of the vacuum seal bags would compress the ice cube tray into a distorted shape.
What happens if you just put the water in the bag, seal it, and freeze it in a shape? Rods might be easier then blocks, but wonder if it would make clear ice?
