Basically made of paprika, cayenne pepper powder, garlic powder, oregano, and other flavorful seasonings, Cajun spice (also called Cajun seasoning) features a bold spicy flavor with a subtle earthiness. Although it contains the combined heat of paprika and cayenne, this seasoning is considered mild because, again, it’s made with a combination of seasonings. Despite being made from a combination of spices, some versions are still hot because different brands pack different amounts of ground peppers in their bottle. For this reason, we recommend testing this alternative first before using it.

Another name for Capsicum oleoresin is Capsaicin oleoresin. Capsaicin is the active component responsible for the pungency and heat in chili peppers, and the oleoresin derived from these peppers is often referred to as capsaicin oleoresin.

So, if bell peppers are in the same scientific classification as cayenne chili pepper, why aren't bell peppers hot? It comes down to a chemical compound called capsaicin. This chemical is the sole reason why a jalapeño is spicy and bell pepper is not. A bell pepper has no capsaicin. Capsaicin attaches itself to the mucous membranes in our mouths which in turn send out the fiery sensation. That heat in your mouth (or hands) will vary greatly depending on what type of chili pepper you've eaten. Peppers are ranked by their heat, or the amount of capsaicin they contain, on a scale called the Scoville Scale. Their capsaicin concentration is given a number on the scale and it is called Scoville Heat Units. Bell peppers do not have capsaicin, so they have zero Scoville Heat Units, therefore they are way at the bottom of the Scoville scale.
