There are many ways, but here is my family's all time favorite way.........tastes perfect!!!!!
Ingredients:
1 litre Kikomen soy sauce
2 Half bag brown sugar
3 4 good shakes HP sauce
4 4 good shakes worcheshire sauce
5 Half litre ketchup
6 1 cup vinegar
7 black pepper, dozen turns with the pepper mill
8 1 cup coarse salt
9 1/2 cup clear corn syrup
10 6 garlic cloves {chopped fine}
Mix all in large container that has a secure lid, add fish with skin on, put in fridge, let sit for 6 hours, take out and turn up or give it a shake. back in fridge for 6 more hours. Take out of fridge and place fish on paper towel skin side down until dry but shiny{approx 1 hour}. Put in smoker, burn 3 pans of wood chips, we use alder/cherry wood half/half. After 3rd pan of chips are done , take out pan and leave fish in smoker another 10 to 12 hours. Wallah, you have the most awesome fish ever tasted my friend. I usually buy a couple of cheap beef round roasts, slice it real thin and do the same for beef jerky, tastes great too.
