Jake….I mix equal parts of Morton Tenderqwik and brown sugar together in a large bowl and blend it thoroughly with a large fork or wire egg whip. I rinse the fish off and rub lots of the sugar mix on the flesh side of the fillets, laying them on top of each other in either a plastic or glass cake dish….11X13 inch or larger. DO NOT USE METAL. The pan gets covered and put in the fridge over night. The next morning I wash the fillets off so none of the sugar or salt is stuck to the fillets, then I lay the fillets on a clean bath towel, skin side down, and fold the towel over the flesh side and press down to dry the fillets as much as possible without schmucking the meat. I fill the smoker with the fish and get the smoke going and just watch the meat for color. When its a nice mahongany color I kill the heat and smoke and let the fish stay right in the smoker until they’re at air temp. I then bring them in and put them in the fridge until cold and then vacuum pack the fillets individually. I fold a piece of paper towel over the end of each fillet in the sealing bag at the open end to help stop any juice from screwing up the seal. Doesn’t hurt a thing.
Rubberduck….I use charcoal in a conventional smoker. For wood I prefer chunk apple and/or pear. I wrap three or four nice chunks in heavy aluminum foil and lay two of these “bombs” right on the charcoal. When the first round of charcoal is about burned out I add new charcoal and a couple more bombs. Even in very cold weather I don’t need to do more than a couple rounds of charcoal and bombs on fish fillets this size. The wood is dry, never, ever soaked. I find apple and pear trees that people want taken down and do it for the wood. I have a friend who’ll take the smaller stuff, but I want thick limbs and trunk wood that I saw into 4″ lengths to dry then split those with a small axe into usable sized pieces.
The expired bombs contain the best home-created charcoal you’ll ever find for grilling food. Steak grill over apple or pear charcoal; is almost sinful good. The trick is to be sure the foil seals the bombs real tight. When super-heated on the charcoal the smoke makes its way out but does not allow the wood inside to flame. I have a fifty gallon yard bag full of this charcoal that I use along with the old standard Kingsford and its amazing what the blend does for the lowly hotdog or bratwurst.
