Note 1 on Salmon: I prefer to buy boneless, skinless salmon in a nice thick piece so it can easily be cut into cubes. I usually find boneless, skinless salmon filets at Trader Joe’s, Target, and many other grocery stores. If you’re at a more boujee grocer with a seafood counter, you can also ask them to remove the skin and even cut it into cubes before packaging it for you. This amount of spice mix will work for anywhere from 1 to 1.5 pounds of salmon (if you’re closer to 1.5 pounds it will be less thoroughly coated and you may want to add a bit more salt when it’s done / after you taste it).
Note 2 on Brown Sugar: If the brown sugar is dry or clumpy, break it apart with your hands or with a fork so that it mixes more easily with the other spices and coats the salmon more easily.
