Cayenne pepper is a popular condiment used to add heat and flavor to various dishes. However, if you're looking for synonyms for cayenne pepper, there are a few other options to consider. One is chili powder, which is made from ground dried chili peppers and often includes other spices like cumin and garlic. Another option is red pepper flakes, which are made from dried and crushed red peppers. Paprika is also a type of ground dried pepper, but it has a milder flavor than cayenne. Finally, if you're looking for a non-spicy alternative, you can try using black pepper or white pepper instead.
