Cajun seasoning is rooted in Louisianna and consists of a base of garlic powder, onion powder, and pepper. It is often combined with several other dried herbs and spices. Blackened seasoning is also rooted in Louisianna and adds paprika, oregano, thyme, and several varieties of pepper. A combination of these two styles results in Chef Andre's Blackened Cajun Seasoning. Made by Old Mansion in Petersburg, Virginia.
