How to cook fish?

I think just enough chili is one of the healthiest ways for great smelling cooked fish :) I also enjoy steamed fish using broth with ginger, garlic and onions. I think when there is just enough to neutralize the smell, fish tastes great. Finally, it seems there is no substitute to washing the fish with lots of water and scrubbing it with some salt before starting to cook it . Cheers :)
