Damn,
I just did the same thing....Wegmans had a 2 for one sale on Smoked Salmon trim at about $6.50 per lb. I love smoked salmon on a bagel with cream cheese!!!!
I froze the second pack and just now looked at it.
Only said to keep it below 35 degrees......nothing about freezing. In the package, it looks fine. I can't see where it would be a problem. I freeze up a lot of Perch and Bass and it is fine.
The only problem I have had is, with the oily Salmon.....
after 3-4 days of my bagel Salmon breakfast's, my a/hole feels like it got converted over from conventional motor oil to fully synthetic!!!!
Be good, Jim
