This is the one I keep coming back to:

this is for 1 fillet of salmon or steelie.

1 teaspoon salt & pepper
1 & 1/2 tablespoons of lime juice not lemon
1 1/2 tablespoon garlic salt or in jar
cop up some fresh rosemary and put in mixing container.
1/2 cube of butter

melt the butter first then add everything else mix and spread over fish both sides either baking or BB-Q, and on the last flip coat the top side of the fish with the rest of the batter and let sit until fish is done. This is my favorite!! Enjoy!
