Mix all the spices together and then blend in a food processor so that you get a finer powder. Place the mix in an old spice jar, it should fit perfectly and can then be stored safely. If you are missing any of the herbs, it won’t be the end of the world to the end taste.
Mix 4 tsp of the Cajun blend with 4 tbsp of light olive oil or grape seed oil thoroughly. You don’t want an oil with much natural flavour as the spices will overpower it anyway.
This is a little bit on the spicy side so you will want to serve it with something cooling and fresh like a cucumber salad.
