1. Paprika
Paprika is a spice made from dried and ground red peppers. It is not spicy and contributes a sweet and slightly smoky taste with its subtle fruity and peppery hints to the seasoning. It also balances the heat from cayenne pepper and other spices.
Visually, the pepper has a rich, warm red color. This vibrant hue adds color to dishes and makes them more appetizing. You can use both regular paprika and smoked paprika for your Cajun seasoning, but if you do not have both, you can substitute it with red chili powder or flakes.
