How to Make It
Season the salmon with a little salt and the pepper. Pour the remaining salt into a large cast-iron skillet.
Place the skillet over high heat until the salt begins to smoke. Put the salmon, skin-side down, on the salt.
Cover, reduce heat to medium-low, and cook 10 minutes or just until the salmon is no longer translucent.
Remove from heat. Lift the salmon fillet from the skin and serve.
