Thanks for the recipe colinh. I've seen a very similar recipe for salmon in a salmon cookbook I have (there's your answer charjohncarter), but haven't ever tried it.
Speaking of that cookbook (and it also relates to some mentions you made in the recipe, colinh) I tried something else in there called brining. I tried to boil sugar & salt in water, then soak the fish in the liquid, and then cook it on the grill. Well I never got the sugar to dissolve into the salty water & I ended up leaving the fish on the coals all night. The next morning I had something similar to salmon jerky that was fairly edible, but the night before was absolutley disgusting.
Like so many other things in life- you try & you win some & you lose some.
