Use a small whisk or fork to mix everything together well. Store in an airtight container in a cool dry place. Note: this recipe makes about 3 Tbsp of salmon rub (enough for 1 whole salmon fillet that’s about 2 lb). Note: This salmon seasoning is very lightly salted. You will need to season your salmon with salt before using this salmon rub. It depends on the size of your salmon fillet.
