A jalapeno at 5000 SHU isn’t anything compared to a pepper who’s Scoville heat rating is in the millions. These peppers can actually be dangerous if not handled with care, but they are the secret ingredient to many hot sauces and other dishes.
For reference, pure Capsaicin has an SHU of 15 million, and Pepper Sprays used for self defense range from 2 to 5 million. The Carolina Reaper is the official hottest pepper in the world. Although others have surpassed its heat, their stability as a variety is still not there, meaning that from pepper to pepper the level of heat varies too much to be officially hotter.
