Still don't quite know what I'm doing when it comes to fish but it wasn't bad! I'm gonna try salting it ahead of time next, this was a frozen filet and I was hungry lol
Vast majority of fish and other seafood is flash frozen on the boat, as it’s a significant food safety issue to do otherwise. What you typically buy as “fresh” fish has been thawed in store.
Only real way to get real fresh, never frozen, fish is to catch it yourself, or know someone who does, or see it actually alive in a tank (in which case flavor majorly suffers due to stress of the animal).
Indeed, the most common method is the "gassing" but there are brands that actually use a dye made from vegetable extract. I just used dyeing in the sense of providing color alteration through artificial means.
