This was the one I had on my computer.
Here is my brine for smoked salmon:
Mix one bag of DEMERARA brown sugar. 1kg or 2.2lbs for you old timers.
One cup of course salt.
Mix these together in a big bowl dry.
That is the mix and then you decide how much fish you have to do, if you have a large batch then you might need to mix two or three bags. But the ratio does not change.
Put the filleted fish in a cooler skin side down until the bottom is full, lay about 1 inch of the mix on top. Now put another layer on top of the mix with the skin side up, it will sandwich the sugar between the meat of the salmon. And you would just repeat that again skin down, sugar, flesh until your fish is gone. Put a frozen jug of water in the cooler when your done ( I use a 2L milk jug) that way the liquid does not go into your brine.
You do not put any liquid in the fish; it will make its own.
If you start it in the morning, then the next day you take out most of the fish and in the bottom of the cooler you will find some of the mix is not dissolved yet. So you give it a good mixing with your hands, until it’s all liquid. It will be very, very cold and you will get an ice cream head ache. So I have a bucket of warm water beside so I can dip my hands in every couple of minutes.
After every thing is mixed, put the fish back in the cooler and the top layer should be pointed so the skin side is up. That way the meat is in the brine.
A couple of times a day I will mix the fish up, you do not have to remove any. You just reach in and give it a good stir with your hands so they all mix up. Make sure when your done the skin side is up again only on the top layer.
I leave my fish in for four days at least, sometimes six days if the pieces are thicker.
I then smoke the fish for only 4 hours so it is nice and moist, I don't like it dried out.
