Skin still on the fillet? Always smoke skin to the grill.
I mix equal parts of Morton Tenderquik and brown sugar together in a bowl with a whisk. The fillets get a good rinsing, then patted dry with a clean towel. Rub a real generous amount of the sugar mixture into the flesh side of the fillets, leaving any excess right on the fish and lay them skin side down in a plastic or glass baking dish and set in the fridge over night. Cover using plastic wrap if a cover for the baking dish isn’t available. Your fillets can be stacked in the dish.
The next morning start the smoker, then go in and rinse the fillets off under cool running water. Pat them dry again with a clean towel. Simply set the fish on the smoker grids skin side down and smoke to desired color or doneness.
Salmon cooks with little heat and doesn’t require a huge amount of smoke. I always aim for a nice mahogany color with the flesh not super dry, but tacky on the surface. Once you have the meat done as wanted, shut down the heat and the smoke, but leave the fish right in the smoker to cool naturally….meaning air temp. Then cool on an open plate or tray in the fridge until cold. Your fish will be very firm and super good eating. It’ll have all the salt need from the Morton product along with cure to help keep the fish in the fridge for a much longer period of time than what salt curing will afford you. Fish going from a warm smoker directly to the fridge can get mushy.
I vacuum seal all my smoked fish. Doing so keeps the smoke in the package and not all over the freezer. It keeps the fish from drying out. When its time to use a package, it goes from freezer to refer until fully thawed and one would never know it wasn’t fresh from the smoker.
Salmon deserves to be enjoyed without all the crap flavorings being mentioned. Think about it…..are these guys doing this to walleye? Save the heavy spices for jerky and snack sticks.
