I love sushi, especially salmon. I chanced a small bite from a Sockeye I caught last year and it was definitely the best raw fish I ever ate. I would love to try some more, especially the rezzy's early in the season. But I am unsure if my at home freezer cools it down enough to do so. We have freezers set to -10F, and all the salmon we catch that isn't eaten fresh gets filleted, vacuum packed, and frozen as soon as it is caught. (Unless it is being smoked) Would it be safe to take a slice?
