All types of peppers are a part of the Capsicum family, which includes both the sweet peppers as well as the hot and spicy ones, often referred to as chili peppers. Fun fact: the heat of a pepper is measured using Scoville heat units (SHU), and this scale goes from o, think bell pepper, to the X Pepper which clocks in at over 3,000,000 (ouch!).Below we broke down each type of pepper, and included their SHU measurements, so you can know exactly when and how much heat you’re adding to a dip or skillet supper. Just be warned that the heat can still vary from pepper to pepper, so one jalapeño could taste milder compared to another.Quick tip for those who can't handle the heat: have some dairy, like yogurt or milk, nearby to help balance the spicy heat in chilis. If you want to simply take the spice level down a notch, remove and discard the seed and whitish ribs before using it.Interested in growing your own peppers?
