I Thanks for getting back to me Wade,
I think that we possibly do cure the same way for Salmon, I cover (lightly) with salt (thicker salt at head than tail) but I set the container on an incline so that the brine drains away from the fillets.
I'll give your brine method a go next time I get some cod and give it a smoke, I've always been reluctant to give it a try just in case I spoil a good bit of fish as it ain't cheep! Have you tried it on Bass?
