"Red chili powder" and "cayenne pepper powder" are both common chili seasonings used in cooking, but they have some differences, including ingredients and spiciness:
Types of peppers:
Red Chili Powder: This term usually refers to chili powder made from a variety of red chili peppers, which can include hot pepper types such as cayenne pepper, bell pepper, or a blend. Such chili powder can take on different flavors and spiciness depending on the type of chili pepper used.
Cayenne Pepper Powder: This is a specific type of paprika derived from the capsicum species "Capsicum annuum". Cayenne pepper usually has a relatively high level of spiciness and its color may vary from red to orange.
Raw materials and colors:
Red Chili Powder: Can be made using different types of red chili peppers and may vary in color from bright red to darker red.
Cayenne Pepper Powder: Made from cayenne peppers, it is usually a bright red-orange color.
Red Chili Powder: The spiciness varies depending on the type of chili pepper used. Some types of paprika may be relatively spicy, while others may be relatively sweet.
Cayenne Pepper Powder: In terms of spiciness, cayenne pepper is usually relatively spicy. Its spiciness is relatively high among chili powders and is generally used in foods that want to add spiciness.
In general, these two types of chili powder can be selected according to personal taste and recipe needs when actually used. If you need more spiciness, you can choose cayenne pepper powder, and if your requirements are less spicy, you can choose different types of red pepper powder.
