Paprika vs. Cayenne: Heat, Color and Flavor Compared

Paprika and cayenne are both dried, ground red fruit of Capsicum annuum.¹² What separates them is what each is grown and blended for. Paprika is sold for color and sweet pepper flavor, with heat optional: the international Codex standard defines paprika as dried Capsicum at 480 Scoville heat units (SHU) or less, and “hot paprika” as above 480 but below 900.³ Cayenne is sold for heat. Its published Scoville figures disagree with each other, but every one of them sits above the 900 SHU line where the Codex standard stops calling a chile paprika.³²⁴⁵⁶

This page compares the ground spices, not fresh cayenne pods.

Side by side

The editorial flavor row is our description. It fits what the specifications say: the La Vera specification calls its sweet type completely sweet with a mild flavor and describes the smoked product as smoky, intense and penetrating.¹² For each spice on its own, see paprika and cayenne pepper.

How much hotter is cayenne?

Much hotter, but no one can give a single multiple, because the figures on each side measure different things. They sit side by side here and are not combined:

How to read this:

• The paprika figures are boundaries, not measurements. The Codex numbers say where a product stops being paprika; they do not say how hot any jar is.³ The Hungarian classes are in mg/kg of capsaicinoids, not Scoville units, and are not converted here.⁹ PepperScale’s two general ratings come from two of its articles, do not agree with each other, and both reach above the Codex ceiling for paprika; Codex is the international standard, so they are shown, not adopted.²⁰²¹
• The cayenne figures belong to their own scopes. The cultivar measurements describe those cultivars in those trials.⁴ The 30,000–50,000 range is attributable to named writers, DeWitt, Chili Pepper Madness and PepperScale, but none cites a measurement behind it.⁵²²¹⁹ The cultivar figures do not show that range is wrong. McCormick Science Institute’s 8,000 has no stated sample or method.²
• The same name can carry two numbers. DeWitt’s approximate scale puts ‘Large Red Thick’ at 2,500–5,000 SHU; the New Mexico trial measured it at 12,900 by HPLC.⁵⁴ New Mexico State University calls the Scoville taste test subjective and HPLC the most accurate method.¹⁰
• Even the lowest cayenne figure is above the hot-paprika band. That is the one comparison the sources support across scopes.

Paprika was not always the mild one. Hungary’s Hungarikum Committee says Hungarian paprika stayed hot until the 1940s.²³ A figure of 15,000 SHU for the hottest paprika also circulates; we found no source for it, and it sits far above the Codex band for hot paprika.

The differences that change a dish

Heat

This is the main one. A tablespoon of sweet paprika over a dish adds color and flavor; the same amount of cayenne makes it fiercely hot. Chili Pepper Madness puts it plainly: cayenne is “quite a bit hotter” than typical mild paprika.²⁴ Because cayenne is used by the pinch and paprika by the spoonful, the two are rarely measured the same way in a recipe. That is cooking judgment, not a measured finding.

Color and flavor

Paprika is often in a dish for its color. The spice trade grades it by color, using ASTA Method 20.1, which reads the absorbance of an acetone extract at 460 nm,¹¹ and the protected Spanish and Hungarian paprikas set minimum color values.¹²⁹ Its red comes mainly from capsanthin and capsorubin.⁸ Cayenne also colors food red, but no color specification or pigment profile for retail cayenne was found, so how the two compare in coloring strength is not known. PepperScale describes the visible difference: cayenne stays within a narrow orange-red, while paprika runs from orange-brown to deep red.¹⁸

Smoke

Only some paprika is smoked. Pimentón de la Vera is dried over holm oak and oak fires,¹² while Pimentón de Murcia is dried in the sun or with hot air.¹³ Cayenne powder brings no smoke. See smoked paprika.

Where each is used

Paprika defines Hungarian goulash and paprikash.²⁵ In Spain, the La Vera specification credits smoke-dried pimentón’s stable color with making it the best preservative for sausages and cured meats.¹² McCormick Science Institute lists red pepper (cayenne) in seasoning blends, meats, pickles and seafood, and in Italian, Indian, Mexican and Caribbean cooking, and describes a mash of red peppers as the key ingredient in Louisiana-style hot sauces.² For more, see cayenne pepper uses.

Can one stand in for the other?

Only partly, because one is mostly color and the other mostly heat. The ratios below come from our substitute pages and keep their labels there.

• Paprika in place of cayenne (Attributed). Chili Pepper Madness says to use double the amount of paprika, and Mashed gives the same doubling.²²²⁶ Neither says how the figure was arrived at. Doubling gives you the color; in our judgment it will not give you cayenne’s heat, since even hot paprika sits below 900 SHU by definition.³ If heat matters, add a pinch of red pepper flakes too. See cayenne pepper substitutes.
• Cayenne in place of hot paprika (Method). The Spice House lists cayenne as a substitute for hot or sharp paprikas, without an amount.²⁷ PepperScale says swapping cayenne for paprika is easier than the reverse but a major jump in heat, so use less.¹⁸ No published ratio exists for cayenne alone. Use a sweet base (sweet paprika, bell pepper powder or ancho) for the bulk and add a small pinch of cayenne per teaspoon, then taste once the dish has simmered. PepperScale publishes a hotter blend, ancho or chili powder cut with an equal part cayenne (Attributed);²¹ by the figures above that is far hotter than any hot paprika. See paprika substitutes.
• Cayenne in place of sweet paprika (Method). Not recommended where paprika is used by the spoonful: you would be adding a hot spice where the recipe wants a mild one. For color alone, a small pinch is the most a dish will usually take.
• Cayenne in place of smoked paprika (Method). You lose the smoke as well as the sweetness. A smoky ingredient such as smoked sea salt can bring some smoke back; no source measures that swap. Smoked paprika substitutes covers better options.

What isn’t known

• No study measures retail paprika and retail cayenne side by side, for heat or for color.
• No Scoville measurement for paprika as a product, or for a named paprika cultivar, was found; only the Codex category boundaries and Hungary’s labeling classes.
• The 30,000–50,000 SHU range for cayenne can be attributed to named writers but not to a published measurement.
• It is often said that hot paprikas contain cayenne. PepperScale says hot paprika may be a mild chile cut with a hotter one, often cayenne, without naming a product or source.¹⁸ No label or specification reviewed here shows it, and the protected paprikas list their own pepper varieties, such as Jaranda, Jariza and Jeromín for La Vera.¹²
• Hungary is often called the world’s leading paprika producer. McCormick Science Institute names Spain, Hungary, China, India and the United States as important producers without ranking them,¹ and no production statistics were checked for this page.
