Most recipes don't mention what type of salt. I would have thought whether it is coarse or fine would affect the penetration and therefore how much you should use. I have used maldon sea salt flakes to good effect, but they are a bit pricey. The coarse grain sea salt has worked well too, whilst the fine seems to leave the salmon too salty (so much so that I have soaked the salmon after curing, which is a bit self defeating!).
As I can't seem to find much salt without anti-caking agents I am going to order some from the shop here. I though I'd get get coarse to use for the dry rubs and fine to use for brines. Does that sound about right?
Cheers.
