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 used to do it by filling a lunchbox cooler with water, letting it freeze, melting off the cloudy ice with hot water, then whacking the resulting slab of clear ice with a rolling pin to get irregular shaped clear iceburgs. Until the cooler cracked.
Now I use a Simply Frozen box, same method really but it makes cubes. And so far (6 years or so) has not cracked.
Directional freezing is the only method that’s worked for me.
