Salmon is the god of fish, love salmon.......Cod is great, mild white fish, better than flounder and way better than tilapia, in fact unless you know for a fact you have tilapia that doesn't come from asia (farm raised) just stay away from it. Its cheap for a reason, trash fish.
You can buy these 2 lb bags of frozen cod. It says to thaw it first, i dont,. Best cooked right on a george foreman grill. Use spices and the foreman sears the outside with the spices all cooked in . Enhance flavor with lemon or use a nice ginger dressing.
Look up Cod tacos!
If you cook your fish right it shouldnt taste fishy. Fresh is always better. Wild caught salmon is better than farm raised.
