Find a container where the salmon fits flat and one that you can put your weight in. I used a pyrex glass 4 by 7 container. Also, find the weight you will be using. I have used cans, jars, tightly pressed shot glasses. Anything that will apply even pressure onto the fish will work.
Rinse and pat the fish dry.
Mix the sugar and salt and put in a flat dish. Dip the salmon on all sides into the salt sugar mix. Make sure the salmon is covered in salt and sugar on all sides.
Place in the container and cover with parchment paper. Add the weight on top and apply pressure to the weight. You can do this with the lid, or with rubber bands.
Put into the refrigerator for 3-4.
Once done with curing, drain off the water. The salt and weight forces water out of the fish and that is normal.
Rinse the salt and sugar off the fish and pat dry again. Also, wash out the container if you will be returning it.
Cut into thin slices and serve with your favorite dishes.
