Start with how ever much Steelhead (Or Salmon) you want to cook.(with skin on) Place fish skin down in pan. Sprinkle fish with pepper, salt and dried dill. Place thin strips of butter on top of fish. Usually 2 thing slices per fillet. Then put slice of butter under 2 edges of each fish. Turn range on medium, cover and cook till fish is pink on the inside.
Take 3 cloves of garlic and place them in a blender. Add 1/4 cup of lemon juice and blend. Add 1/4t of salt and 1/2t of pepper. Melt one stick of butter and add slowly while blending. (sauce can be frozen and reheated for another meal as well.)
