>>9942011My favorite fish is whatever fish I happen to be eating at the time, provided it has been properly cooked and served with a suitable range of other edible items, to make a balanced meal.
Sure, sometimes I choose to eat salmon and that's because it's the one I currently want to eat most. But the next time, I might prefer tuna, or cod, or haddock, or monk-fish, or halibut ..... etc..
Same with everything else in life. I feel pity for anyone who cannot think beyond just one favorite thing (in any sort of category)
