Rinse your fillet in cold water and pat dry. Freeze it for 24 hours minimum. Thaw it in the fridge.
Brush with your fingers on top of the fillet and remove bones if you feel any. Pick the bones out with your fingers or with a tweezer.
Put your salmon in a dish covered with plastic wrap or aluminum foil.
Sprinkle the sugar evenly on top. Add the salt. Put heavier with salt on the thick middle part and less on the thin parts.
Add some pepper and chopped fresh dill on the surface if you want to. Pepper can be ground somewhat with a mortar and pestle.
Wrap the fillet tightly in the plastic foil.
Let the salmon cure in the fridge for at least a day. 36-48 hours is the average.
After curing, wipe away the salt and spices. You can rinse it and pat it dry with a paper towel. Slice the flesh thinly with a sharp knife (without the skin).
