Mix the 30 grams salt, 40 grams evaporated cane sugar and 1 teaspoon black pepper together along with any other herbs of flavorings you would like to use. If you are using fresh herbs, be sure to dry them thoroughly with paper towels before mixing them in, otherwise your salt will clump together.

On a tray large enough to fit your side of salmon, lay down a sheet of plastic wrap large enough to completely wrap your salmon and then sprinkle a layer of the salt and sugar mixture that's about the size and shape of your salmon.
Place the 1 side of salmon skin-side down on the layer of salt and sugar, and then cover with more salt. Depending on the size and thickness of your side of salmon you may not need all of the salt.
1 side of salmon
Wrap the plastic wrap around the fillet, but leave the ends open so the liquid that comes out of the salmon can drain off.
Place a weight on top of the salmon. I used a tray that's slightly smaller than the one the salmon is in and added cans to weigh it down. Feel free to get creative here. As long as you're applying even pressure to the whole fillet, your solution should work just fine.
Place the salmon with weights in the refrigerator and tuck something (like a wad of paper) under one side so that the tray is tilted. This helps the liquid that comes from the salmon drain off as the fish cures.
The curing time depends on how thick the salmon is, but it should be done in 2-3 days unless your salmon is very thick. You can tell it's done by slicing into it. The meat goes from opaque to translucent as it cures, so as long as it's the same color all the way through it should be done. If the center is more opaque than the edges, it probably needs some more time.
When the salmon is finished curing, quickly rinse off any excess brine from the surface of the salmon and pat dry with paper towels.
Use tweezers to pick out the pin bones along the center of the fillet. Then you should be able to peel the skin off the salmon from the head to the tail
Slice the lox as thin as possible with a long sharp knife (a carving knife or sashimi knife will work the best).
