O.K, I have one that we have been working with for a couple of years that started out as a white fish recipe and we have found that it works great on other fish. It goes like this. In a large tupperware container mix-

1> quart kikioman soy sauce
2> 3/4 cup brown suger
3> 3 oz real lemon juice
4> garlic powder ( some)
5> 1/4 cup salt
6> 1 can frozen apple juice- 3 cans water
the apple juice is the key here.

soak in brine at least over night. Then, allow to dry on the racks for at least a couple of hours before you put it in the smoker. I use a little chief, and alder wood seems best. Very tasty.. I use two pans of chips right away and another about half way thru. Enjoy!!
