Stir well to ensure all the spices are evenly distributed throughout the mixture.
Taste the seasoning blend and adjust the salt and cayenne pepper according to your preference for saltiness and spiciness.
Once satisfied with the flavor, transfer the Cajun seasoning to an airtight container or spice jar for storage. To make this easy, put spices on a paper plate and fold plate in half, and the seasoning will slide in without making a mess.
Store the Cajun seasoning in a cool, dry place away from direct sunlight.
