Paprika vs. Cayenne: Heat, Color and Flavor Compared

Paprika is for color and sweet pepper flavor. Cayenne is for heat. Both are the dried, ground red fruit of Capsicum annuum, and the difference is what each is grown and blended for. 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 900.¹ Cayenne’s published Scoville figures disagree with each other, but every one of them sits above that 900 SHU line where Codex stops calling a chile paprika.

We’re comparing the ground spices here, not fresh cayenne pods.

Side by side

The flavor row lines up with 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.⁶ For each spice on its own, see paprika and cayenne pepper.

How much hotter is cayenne?

Much hotter. Nobody can give you a single multiple, though, because the figures on each side measure different things. They sit side by side here, uncombined:

How to read this:

• The paprika figures are boundaries, not measurements. The Codex numbers say where a product stops being paprika. They don’t tell you how hot any jar is.¹ The Hungarian classes are in mg/kg of capsaicinoids, not Scoville units, and we haven’t converted them.³ PepperScale’s two general ratings come from two of its articles, don’t agree with each other, and both run past the Codex ceiling for paprika. Codex is the international standard, so we show them but don’t go by them.¹³¹⁴
• The cayenne figures belong to their own scopes. The cultivar measurements describe those cultivars in those trials.¹⁶ The 30,000–50,000 range traces to named writers (DeWitt, Chili Pepper Madness and PepperScale), but none of them cites a measurement behind it.¹⁸¹⁹¹² The cultivar figures don’t prove that range wrong. McCormick Science Institute’s 8,000 comes with no stated sample or method.¹⁵
• The same name can carry two numbers. DeWitt’s approximate scale puts ‘Large Red Thick’ at 2,500–5,000 SHU, while the New Mexico trial measured it at 12,900 by HPLC.¹⁸¹⁶ New Mexico State University calls the Scoville taste test subjective and HPLC the most accurate method.⁴
• Even the lowest cayenne figure is above the hot-paprika band. That’s the one comparison the sources support across scopes.

Paprika wasn’t always the mild one. Hungary’s Hungarikum Committee says Hungarian paprika stayed hot until the 1940s.²¹ You’ll also see a figure of 15,000 SHU for the hottest paprika. 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 big 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.²² Cayenne goes in by the pinch and paprika by the spoonful, so recipes rarely measure them the same way.

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,⁵ and the protected Spanish and Hungarian paprikas set minimum color values.⁶³ Its red comes mainly from capsanthin and capsorubin.² Cayenne colors food red too, but we found no color spec or pigment profile for retail cayenne, so no source says how the two compare in coloring strength. PepperScale describes what you can see: cayenne stays in a narrow orange-red range, while paprika runs from orange-brown to deep red.¹¹

Smoke

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

Where each is used

Paprika defines Hungarian goulash and paprikash. In Spain, the La Vera specification credits smoke-dried pimentón’s stable color with making it the best preservative for sausages and cured meats.⁶ Red pepper (cayenne) goes into seasoning blends, meats, pickles and seafood, and into Italian, Indian, Mexican and Caribbean cooking. A mash of red peppers is the key ingredient in Louisiana-style hot sauces. More in cayenne pepper uses.

Can one stand in for the other?

Only partly, since 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.¹⁹²³ Neither says where the figure comes from. Doubling gets you the color. It won’t get you cayenne’s heat, since even hot paprika sits below 900 SHU by definition.¹ If heat matters, add a pinch of red pepper flakes too. See cayenne pepper substitutes.
• Cayenne in place of hot paprika. The Spice House lists cayenne as a substitute for hot or sharp paprikas, with no amount.²⁴ PepperScale says swapping cayenne for paprika is easier than the reverse but a major jump in heat, so use less.¹¹ Use a sweet base (sweet paprika, bell pepper powder or ancho) for the bulk, add a small pinch of cayenne per teaspoon, and taste once the dish has simmered. PepperScale publishes a hotter blend, ancho or chili powder cut with an equal part cayenne (Attributed).¹⁴ By the figures above, that’s far hotter than any hot paprika. See paprika substitutes.
• Cayenne in place of sweet paprika. Skip it where paprika goes in by the spoonful. You’d be adding a hot spice where the recipe wants a mild one. For color alone, a small pinch is usually the most a dish will take.
• Cayenne in place of smoked paprika. You lose the smoke as well as the sweetness. A smoky ingredient like smoked sea salt can bring some smoke back, though no source measures that swap. Smoked paprika substitutes has better options.

What isn’t known

• We found no Scoville measurement for paprika as a product, or for a named paprika cultivar. There are only the Codex category boundaries and Hungary’s labeling classes.
• The 30,000–50,000 SHU range for cayenne traces to named writers but not to a published measurement.
• You’ll often read 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.¹¹ No label or spec we reviewed shows it, and the protected paprikas list their own pepper varieties, like Jaranda, Jariza and Jeromín for La Vera.⁶
• 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,²⁵ and we didn’t check production statistics for this page.
