Salmon was vacuum sealed a couple months ago but smelled a little burnt and a small amount (1/8" deep x 2" long by 1/4" wide) discolored. I generously cut off the discolored bit but wondering if the rest will taste bad.
Edit: It turned out great! indistinguishable from un freezer burnt.
A trick I use with questionable fish is to soak the fillet in milk after it thaws for 20 min to 2 hours. Pat it dry and glaze/season. It usually takes any “fishyness” smell/flavor out of it.
