Ask for the head and most fish counters will hand it over for next to nothing, sometimes free. That's strange, because the cheeks and the collar are the richest meat on the whole salmon. They sit close to the bone, they cook fast, and they take charcoal smoke better than a fillet ever will.
Split the head lengthwise so both halves lie flat and you have two pieces that behave a little like small steaks. Hard sear on the direct side to crisp the skin, then over to the cool side under a lid where the miso-maple butter can caramelize instead of burning. The glaze earns its keep: miso for salt and depth, maple for the sugar that browns, Maggi for a savory low note underneath, and enough butter to keep basting until the cheek flakes away from the bone with a fork.
