Why mess with the classics?
I cross referenced salmon recipes from three separate cookbooks (1856, 1905, 1922) and they are essentially the same: sprinkle the salmon with salt, pepper, and butter. Broil/bake at a low temperature. Garnish with parsley.
Substitute the butter for olive oil and you have your basic 21st century salmon recipe.
