Cayenne Vs Paprika: What's The Difference?

What is cayenne pepper?

Cayenne pepper is a spice made by drying and grinding cayenne chili peppers (Capsicum annuum, a specific variety). The dried peppers are typically thin, curved, bright red, and quite hot. After drying, they're ground into a fine powder. Cayenne pepper has a Scoville Heat Unit rating of 30,000-50,000 SHU, putting it firmly in the medium-hot range (much hotter than jalapenos at 2,500-8,000 SHU, but much milder than habaneros at 100,000-350,000 SHU). The flavor is sharp, hot, and slightly fruity with very little sweetness. Cayenne is essential in many global cuisines: Cajun and Creole cooking (gumbo, jambalaya), Indian dishes (especially South Indian curries), Mexican cooking, and African cuisines. A pinch goes a long way; cayenne is typically used in much smaller amounts than other red pepper powders like paprika or chili powder.

What is paprika?

Paprika is a spice made by drying and grinding sweet red peppers (Capsicum annuum, various sweet varieties). The standard paprika is made from peppers with very low capsaicin content, producing minimal heat (100-1,000 SHU, with most commercial paprika near the lower end). The flavor is mild, slightly sweet, and slightly fruity. Paprika provides vibrant red color to dishes without significant heat. Hot paprika exists as a separate product (made from spicier pepper varieties), but standard 'paprika' on most spice shelves is the mild variety. Smoked paprika (Spanish pimentón) is a separate product with intense smoky character. Major paprika varieties include Hungarian paprika (with several heat grades) and Spanish paprika (sweet, bittersweet, or hot). Paprika is essential in Hungarian goulash, Spanish paella, deviled eggs, and Spanish-style dishes.

How do cayenne and paprika compare?

Heat differs dramatically: cayenne is 30,000-50,000 SHU; standard paprika is 100-1,000 SHU. The ratio is about 30-50 times more heat in cayenne. Source peppers differ: cayenne uses spicy cayenne chili peppers; paprika uses sweet bell peppers and similar mild varieties. Color is similar (both bright red), though cayenne is sometimes more orange-tinted. Flavor differs significantly: cayenne is sharp, hot, slightly fruity; paprika is mild, sweet, fruity without heat. Usage amounts differ dramatically: cayenne is used in pinches (1/8-1/4 teaspoon at a time); paprika is used in larger amounts (1 tablespoon or more). Cooking applications differ: cayenne adds heat as a primary feature; paprika adds color and mild flavor. Substitution requires major adjustments.

Can you substitute one for the other?

Not directly due to dramatic heat difference. To substitute paprika for cayenne: the dish will completely lose heat; add a small amount of hot sauce, fresh chili peppers, or another hot pepper powder (red pepper flakes) to add heat back. To substitute cayenne for paprika: the dish will become significantly spicier; use only 1/30th to 1/50th the amount of cayenne to roughly match the heat level desired from paprika, but understand the dish will still be much hotter than expected. For color and mild flavor, paprika is essential and cayenne won't work; for heat as a primary feature, cayenne is essential and paprika won't work. For dishes wanting both color and moderate heat, hot paprika (smoked or not) provides middle-ground; chili powder (a blend) is another option for medium heat with color.
