As its name implies, chili powder works well for making meaty, bean chili. This convenience mix includes ground chili peppers and spices like cumin, garlic powder, oregano and salt. You can add it to your chili or other recipes without worrying about how to balance the spices.
Bell peppers belong to the same nightshade (or Solanaceae) plant family as tomatoes, eggplants, potatoes, and chili peppers. The peppers in this nightshade plant family are scientifically classified as Capsicum annuum, and this is applied to both the sweet (like bell peppers) and hot peppers (like jalapeños and cayenne) varieties in this particular plant family. There are many different cultivars of Capsicum, or peppers, which are classified under different species names. For example, the habanero chile is categorized under the Capsicum chinense.
