What's the Difference Between Cayenne Pepper, Paprika, Red Chili Pepper, and Ground Red Pepper?

Although each of these ground ingredients shares a similar appearance and texture, these flavorful spices have unique spice levels, flavor profiles, and uses.

  • Cayenne pepper is a super spicy chili that rates high on the Scoville scale—a method for measuring peppers' heat levels.
  • Ground paprika is produced by grinding numerous peppers and can have a flavor ranging from sweet to fiery.
  • Ground red pepper and red chili powder are both generic spice names that at times refers to cayenne, but can also include other red chilies.

Despite its name, black pepper is unrelated to any of these bright red spices, and comes from the fruit of a flowering vine, rather than the pepper family.

What Is Cayenne Pepper?

Typically found in the spice aisle of the grocery store as a finely ground powder, cayenne is a hot pepper that can add a punch of heat to any recipe, from homemade hot sauce to chili con carne. This staple of Mexican cuisine is native to South America and starts as small, thin, bright red pepper before being dried and ground down to cayenne pepper powder.

With a hot, fiery taste, cayenne is one of the main ingredients of Tabasco sauce, and is commonly used in a wide range of world cuisines, like Creole, Asian, Indian, Thai, Chinese, Korean, and more. Belonging to the Capsicum Annuum family of plants, cayenne is related to a number of peppers, including jalapenos, bell peppers, and New Mexico chili peppers.

What Is Paprika?

Paprika is a unique ground spice that can be made from multiple kinds of peppers, resulting in distinct flavors and heat levels. Despite its fiery red color, not all paprikas are spicy. When cooking with paprika, it is imperative to know which of the three types of paprika is being used to avoid imbalances of flavor.

Sweet paprika (aka Hungarian paprika), which is made primarily from ground red bell peppers, is a more subtle spice used primarily as a garnish to add color to dishes. On the other hand, hot paprika (aka Spanish paprika), which is made from ground chili peppers or a combination of chili and bell peppers, can have a heat level comparable to other ground red chilies. Smoked paprika is made when the chili and/or bell peppers are smoked before getting ground into a powder, resulting in a, you guessed it, smokier flavor.

What Are Ground Red Pepper and Red Chili Powder?

This generic form of ground chili pepper—which can be labeled by spice manufacturers as ground red pepper or red chili powder—has a similar finely ground, bright red appearance to cayenne and paprika, but can be made from a variety of ground chilis in the Capsicum family of peppers.

However, the majority of ground red chili pepper products found in the spice aisle, including Mccormick’s popular spice, are made from ground cayenne peppers. In general, red chili powder and ground cayenne can be used interchangeably when a recipe calls for one or the other.

Can You Use Cayenne Pepper, Chili Powder, and Paprika Interchangeably?

Despite the similarities in appearance, these three ingredients can’t necessarily be used interchangeably in all recipes. While fresh cayenne is a consistent source of earthy, spicy heat, chili powder and paprika are more unpredictable ingredients.

The flavor and heat level of a given chili powder can fluctuate depending on the ingredients, so while a super-hot chili powder could at times be swapped for cayenne, it is not guaranteed to be a good substitute. Generally, ground red pepper and red chili powder can be used as cayenne pepper substitutes, as they are frequently made from the same pepper.

Paprika comes in a variety of spice levels and flavors, ranging from sweet and mild to spicy and smokey. Substituting cayenne, or any kind of dried chili pepper, for sweet paprika would certainly affect the overall flavor of the dish. However, hot paprika can be used as a suitable substitute for spicier ground peppers.
