Also break the vacuum seal when you take it out to thaw.
I leave sulphite cured roe in the garage thawed for a few days at a time when I’m on my set off. Just don’t leave lots of borax with it or it will suck the life out of it
I've noticed that too. Good point. Borax is great stuff but it may dry your roe out more than you'd like. After mine thaws from the freezer I'll dump most of the borax out into a container. I'm cheap so I'll save it. After I'm done fishing that roe if there is some left over I use that borax to dump back in the container to make sure it's covered/protected in the freezer.
Another tip I've heard: keep your bait and roe especially in the deep freeze, not fridge freezer. I've heard that the auto defrost on the fridge freezer is not the best for bait longevity. They say the deep freeze, as long as it does not have auto defrost, is better as it stays at a consistent temp. Not warming up and cooling down repeatedly like the auto defrost kind. I've never tested this theory, I just keep it in the deep freeze.
