Salmon really has its own unique taste which doesn’t really resemble cod in any noticeable way. Many people use other foods to compliment salmon along with seasonings such as pepper as well as onions, especially when it is a fillet.
Salmon does not have a very fishy taste like some people think, unless of course it has started to go bad. It is important that you throw away the salmon that you have brought home from the store if it is malodorous or has an unusual taste. Both of these things can be signs of bacterial infection which can lead to serious illness if they are ingested.
