Carolina Reaper

Also known as carolina reaper pepper, HP22B, reaper chilli, reaper pepper

Quick answer

A deliberately bred superhot chilli, recognised as the hottest in the world by measurement for most of the decade after 2013. It is a crossing programme rather than a crop with a tradition, and its published Scoville figure is a laboratory average for a sample rather than a property of any individual pod.

Forms

Where the forms of a spice differ enough to need separate answers, they get them. Most spices do not appear here; these do because treating their forms as interchangeable produces a dish that is wrong.

Fresh pods

A specialist mail-order product rather than a shop item. Fruity, floral and extreme, with a thin wrinkled wall and the characteristic tail.

Flavour:

Apricot and citrus for a second, then heat that builds for half a minute and declines over several.

How to use it:

Gloves, and do not touch your face afterwards regardless. Use a sliver, or a whole pod pierced and lifted out of a pot. Wash board and knife with detergent rather than water, since capsaicin is fat-soluble.

Culinary conventionFollows from the recorded concentration and the fat-solubility of capsaicin.

Not interchangeable with powder

Powder cannot be removed from a dish and fresh pods can, which at this concentration is the difference between a seasoned dish and a ruined one.

Ground Reaper

Milled dried fruit, sold in very small jars. The commonest retail form and the one that commits — once it is in, it is in.

Flavour:

Concentrated heat over a raisin-like sweetness, fading in aroma over months while the heat does not diminish at all.

Culinary conventionFollows from the stability of capsaicin against the volatility of the aroma compounds.
How to use it:

Measured in fractions of a quarter-teaspoon for a whole dish, added early enough to taste before committing further. An old jar is exactly as hot as a new one and tastes of less.

Culinary conventionFollows from the recorded stability of capsaicin relative to the aromatics.

Not interchangeable with fresh

Not a convenience version of the pod. It removes the cook's ability to stop, which is the one technique that makes a superhot usable at home.

Other names

What this spice is called elsewhere, and where the translation is not clean.

Names:
  • Carolina Reaper

    English — United States

    A cultivar name and effectively a brand — it was bred and named by a single grower in South Carolina, and "HP22B" is its development designation. It has no traditional or vernacular names anywhere, which is unusual in this dataset and is a fact about how recent it is.

Culinary conventionRecorded to make the absence explicit. Almost every entity here carries names from several languages; this one has a cultivar name and a lab code, because it is fifteen years old.

Flavour and aroma

Flavour:

Sweet and fruity for a moment and then nothing else registers. There is a genuine flavour there — it is a habanero relative and tastes like one — but at the concentrations involved almost nobody experiences it, because the capsaicin overwhelms the sensory system within seconds. Used in fractions, in a sauce, the fruit comes through.

Aroma:

Fruity and floral, closely related to habanero — apricot and citrus with a sweetness that has nothing to do with sugar. It smells pleasant and unremarkable, which is the last thing most people expect of it.

Colour:

Bright to deep red when ripe, with a rough, bumpy, wrinkled skin and the characteristic thin tail. Dried pods darken to a deep brick.

Strong evidenceSources: Handbook of Herbs and Spices
Texture:

Thin-walled and wrinkled with very little flesh, drying readily. There is nothing structural to cook with here.

Culinary conventionEstablished practice, consistent with the recorded fruit structure.

Heat

Pungency scale: scoville

Scoville:
1400000–2200000 SHU (typically 1600000 SHU)
Reasonable evidenceSources: Note on Capsicums; Handbook of Herbs and Spices

Averages around 1.6 million with individual assayed pods reported well above 2 million. Both ends of this range are laboratory measurements of samples: growing conditions move the figure substantially, pods from one plant differ, and no packet in a shop has been assayed.

In practice:

Beyond any culinary scale. Roughly twice ghost pepper and several hundred times a jalapeño, with a delayed onset and a very long decline.

Strong evidenceSources: Handbook of Herbs and Spices
Pungent compounds:
  • Capsaicin
  • Dihydrocapsaicin
Established factSources: Note on Capsicums; Chemistry of Spices

The Scoville scale was devised in 1912 as a dilution test scored by a human panel, and it was never intended for concentrations at which a panel cannot taste anything. Modern figures come from chromatography and are converted into Scoville equivalents for continuity, which is why the numbers quoted for this pepper carry a precision the original method could not have produced.

Key compounds:
  • Capsaicin The heat, at roughly two hundred times the concentration of a jalapeño.
  • Esters and terpenes The apricot-floral aroma inherited from its habanero parentage, and the reason a very small quantity contributes flavour rather than only burn.

Pairings

Ranked by how well established the combination is, with the reason and the caveats attached.

Foods

Apple

Strong

The pairing that lets the pepper taste of something. Reaper is a habanero relative and carries the same apricot-floral aroma, which is imperceptible at the quantities it is usually eaten in and comes through clearly in a sweet fruit preparation where a fraction of a pod is doing the work. Sugar and acid make the heat approachable without reducing it, so a hot jelly or chutney is one of very few contexts where this chilli reads as an ingredient rather than a stunt.

How: A sliver in an apple or mango chutney; In a hot jelly served with cheese or cold meat

Add alongside: Lemon, Sugar, Ginger

  • Sugar and acid change how the heat is experienced and do not reduce it. The quantity still needs to be a fraction of a pod.
Culinary conventionSources: Established culinary practice

Capsaicin is fat-soluble and binds to the receptors reporting heat; casein strips it away, which is why dairy relieves the burn and water does not. At Reaper concentrations that stops being a serving suggestion and becomes the mechanism by which a dish is edible at all — and a yoghurt marinade also distributes the heat evenly rather than leaving it in pockets.

How: A yoghurt marinade, which moderates and distributes at once; Raita or soured cream served alongside anything made with it

Add alongside: Cumin, Mint

  • It works on contact rather than in advance. Drinking milk before eating does nothing useful.

Pork

Good

Pork is fatty and mildly sweet, which is the combination that carries an extreme chilli best: the fat dissolves and distributes the capsaicin so the heat arrives evenly rather than in bursts, and the sweetness meets the fruit note. It is the same reasoning that puts ghost pepper with pork in Naga cooking, applied to a hotter relative.

How: A whole pierced pod in a slow-cooked pork dish, removed before serving; A trace of powder in a rub, alongside a milder chilli supplying the flavour

Add alongside: Garlic, Paprika, Sugar

  • Fat distributes capsaicin thoroughly and irreversibly. Once it is rendered through the dish there is no removing it.

If you have no carolina reaper

What to use instead, and — more usefully — where each replacement stops working.

Ghost pepper

Good match

The obvious step down and a genuinely good one, because both are Capsicum chinense and share the apricot-floral character underneath the burn. Ghost pepper runs roughly half the heat on the published midpoints, so a dish built for Reaper and made with ghost pepper tastes right and is merely extreme rather than beyond scale. It also has a food tradition to borrow technique from, which Reaper does not.

How the replacement compares on each sensory axis
FlavourAromaColourHeat
closeclosecloseless

Works for

  • Any cooked dish where Reaper was supplying heat and a fruit note
  • Hot sauces, where ghost pepper is an established base
  • Cooks who want a superhot they can actually taste around

Does not work for

  • Matching the heat by quantity, which produces a dish tasting overwhelmingly of chilli rather than a scaled one
  • Anything sold or served as containing Carolina Reaper

The reverse direction is not a substitution but an accident. Reaper in place of ghost pepper at the same quantity roughly doubles the heat of a dish that was already at the edge of edible.

Habanero

Acceptable

Habanero is one of Reaper's parents and still tastes like it at perhaps a fiftieth of the heat, so this is the swap that keeps the flavour and abandons the premise. For anyone who wanted a fruity chilli rather than an extreme one it is the better ingredient; for a recipe that specified Reaper deliberately it is a different dish.

How the replacement compares on each sensory axis
FlavourAromaColourHeat
closecloseclosemuch less

Works for

  • Any dish where the apricot-floral note was the point and the heat was tolerated
  • Cooking for people who will actually eat it
  • Salsas, marinades and sauces at ordinary quantities

Does not work for

  • Recipes where the extreme heat is the stated purpose
  • Closing the gap with quantity, which would take a quantity nothing could carry

Recorded because it is the honest recommendation for most people who go looking for Reaper. The pepper it is descended from does the flavour part of the job and none of the harm.

Preparation and use

A fraction of a pod, a whole pod you can remove, gloves, and ventilation. Carolina Reaper is used in quantities most kitchen measures cannot deliver, so the practical technique is infusion — pierce a pod, put it in the pot, take it out when the heat is where you want it — rather than chopping. The onset is delayed by twenty to thirty seconds, which is long enough for someone tasting to conclude it is manageable and add more, and that is how most accidents happen. Do not grind it indoors without ventilation: capsaicin at this concentration is an airborne irritant and the result affects everyone in the building. Wash hands, board and knife with detergent rather than water alone, because capsaicin is fat-soluble and water simply relocates it. Dairy relieves the burn and water does not, for the same reason. And pair it with something sweet and acidic if you want to taste the pepper rather than only feel it, because underneath all of that it is a habanero relative and tastes of apricot.

Culinary uses:

Hot sauces above all, and snack seasoning, which is where nearly all of it goes. In cooking it is used in fractions of a pod for heat in chilli, curries, marinades and pickles, generally alongside a milder chilli that supplies the flavour. It works with pork, beef, mango, pineapple, lime and tomato, and its fruity character means it belongs with sweet and acidic things far more than its reputation suggests — a very small quantity in a mango hot sauce is the use that shows what it actually tastes of.

Strong evidenceSources: Established culinary practice
What each treatment does:
  • grinding Produces an airborne irritant in quantity. Grinding dried Reaper in an unventilated kitchen is genuinely unpleasant for everyone in the building and is the practical reason powder is bought rather than made.
  • infusing The only controllable domestic technique. A fraction of a pod in a pot, removed once the heat is where it should be, is how a chilli at this concentration becomes usable rather than merely survivable.
  • frying Capsaicin is fat-soluble, so frying disperses it completely and irreversibly through a dish. With a superhot this is the opposite of what a cook usually wants.

Storage and freshness

Storage guidance by form
FormGood forConditionsFridge
Fresh0–1 monthsRefrigerated in a paper bag, or frozen whole.Yes
Powder6–12 monthsAirtight, cool, dark and clearly labelled. This is the one spice in the dataset where mistaking the jar has consequences beyond a spoiled dish.
How to test it:

Smell it. A good powder smells fruity and sweet under the pungency and an old one smells of dust. There is no test for the heat, because the heat does not go — which is the point worth carrying away from this section.

Culinary conventionExercises the volatile aromatics, which are the only component that degrades.
Signs it has gone:
  • Fresh pods gone soft, shrivelled or brown at the stem.
  • Powder faded from red towards brown.
  • No fruit smell under the burn.
  • Mould on dried pods, which means discarding them.
Culinary conventionObservable signs corresponding to the recorded degradation mechanisms.

Quality is not the same as safety

Faded aroma is a quality matter and mould is not. The distinctive caution here is not about age at all: capsaicin at this concentration is a genuine skin and eye irritant, an old jar is exactly as potent as a new one, and gloves, ventilation when grinding and a clear label are properties of the compound rather than of its condition. SpiceHQ holds no clinical or toxicological source on capsaicin at these concentrations and makes no assertion about the consequences of eating it.

Buying and quality

Whole or ground:

Buy whole if you intend to cook with it and powder if you intend to season with it, and understand that these are different activities at this concentration. A whole pod can be pierced, simmered and lifted out when the heat is where you want it, which is the only domestic technique that makes a superhot controllable. Powder commits: the quantity separating seasoned from inedible is smaller than a kitchen measure can reliably deliver, and it cannot be taken back out. If the honest purpose is a dare rather than a dish, none of this applies and none of it is advice.

Editorial judgementFollows from the recorded concentration and from the removability of whole fruit.
What to look for:
  • Powder: buy the smallest jar sold. A domestic kitchen will not finish a large one before the flavour goes, and the heat will still be there.
  • Check whether the product is the pepper or an extract — extracts are a different thing entirely and carry none of the fruit character.
  • Fresh or dried whole pods in preference to powder where the dish allows, because whole fruit can be removed and powder cannot.
  • Treat any Scoville figure on packaging as marketing. Nothing at retail has been assayed.
  • Dried pods should bend rather than shatter and smell fruity when torn.
Culinary conventionThe first three follow from the recorded storage and heat behaviour; the fourth follows from the recorded assay practice.Sources: Handbook of Herbs and Spices
Grades:

No consumer grade exists. Commercial lots destined for extract are assayed for capsaicin content by chromatography and reported in Scoville equivalents; retail packaging quotes record figures that describe neither the lot nor the pod in the packet.

Botany

Scientific name:
Capsicum chinense Jacq.
Established factSources: Plants of the World Online

Bred from Capsicum chinense stock — reportedly a Pakistani Naga crossed with a Red Habanero — and it remains within that species rather than being an interspecific hybrid as ghost pepper is.

Family:

Solanaceae

The nightshade family.

Part used:
fruit
Established factSources: Plants of the World Online
The plant:

A compact plant bearing small, wrinkled, red fruits of four to six centimetres with a distinctive scorpion-like tail — a thin pointed protrusion at the base that is the cultivar's visual signature and the reason it is recognisable in a photograph.

Reasonable evidenceSources: Handbook of Herbs and Spices

Commonly confused with

  • Ghost pepper

    The pepper it displaced, and the more useful of the two to cook with. Ghost pepper is a natural landrace hybrid with a food tradition in Assam and Nagaland; Carolina Reaper is a bred cultivar with none. Reaper is roughly twice as hot on the published midpoints and shares the fruity C. chinense character, so ghost pepper is the sensible step down when a recipe names Reaper.

  • Habanero

    One of its parents, and the flavour it still tastes of underneath — the same apricot-floral character at perhaps a fiftieth of the heat. Habanero is what to reach for when the fruit note is wanted and the burn is not.

  • Trinidad Scorpion, Pepper X and the other record cultivars

    A succession of bred superhots that have traded the record between them. They are close in heat and in breeding intent, and none has a culinary tradition; a recipe naming any of them is generally naming a heat level.

Where it comes from and how it is made

Origin:

Rock Hill, South Carolina, where it was bred by Ed Currie over roughly a decade and released commercially in 2013. It has no centre of origin in the sense the rest of this dataset uses the term, because it did not come from anywhere — it was made.

Reasonable evidenceSources: Handbook of Herbs and Spices
Grown in:
  • US (South Carolina) origin
  • GB notable producer. Grown under glass for the hot-sauce and novelty trade.
  • IN notable producer
  • AU notable producer
Reasonable evidenceSources: Handbook of Herbs and Spices
Harvest:

Picked ripe red by hand with skin protection. The great majority of the crop goes to extract, sauce and powder rather than to fresh sale, and fresh pods are essentially a specialist mail-order product.

Reasonable evidenceSources: Handbook of Herbs and Spices
Processing:
  1. PickingHand-picked at full red ripeness, with gloves — capsaicin at this concentration irritates skin on prolonged contact.Why: Capsaicin peaks at full ripeness.
  2. Drying or extractionDried whole and milled to powder, or processed to oleoresin capsicum for sauces and industrial use. Very little is sold fresh.Why: Shelf stability and, for the extract trade, a standardised capsaicin concentration that the fruit itself does not offer.
  3. Laboratory assayCommercial lots are measured by high-performance liquid chromatography and reported in Scoville equivalents. This is where the published figures come from.Why: Recorded because it is the step people are quoting when they cite a number, and it measures a sample rather than a pod.
Reasonable evidenceSources: Handbook of Herbs and Spices; Note on Capsicums
Grading:

No consumer grading standard. The trade specifies capsaicin content by assay for extract and sauce manufacture; nothing on a retail packet is a grade, and figures printed on novelty products are marketing rather than specification.

Reasonable evidenceSources: Handbook of Herbs and Spices
Cultivation:

A commercial and hobby crop rather than an agricultural one, grown from seed under glass in temperate climates and in the open in the southern United States. Germination is slow and the season long, which is true of the superhots generally.

Reasonable evidenceSources: Handbook of Herbs and Spices
Climate:

Warm, humid and long-season, like most Capsicum chinense. Heat expression varies substantially with growing conditions — water stress in particular raises capsaicin — which is a large part of why individual pods differ so much from the published figure.

History and trade

The shortest history in this dataset. Bred in South Carolina over roughly a decade from Capsicum chinense stock, released in 2013, and recognised by Guinness as the hottest chilli in the world that year — a position it held until Pepper X, from the same breeder, displaced it in 2023. It has no traditional cuisine, no regional name and no documented use before its own creation, which makes it genuinely different in kind from every other entry here: a spice with a launch date rather than a provenance.

Reasonable evidenceSources: Handbook of Herbs and Spices
Trade:

A niche trade in dried pods, powder and oleoresin, driven by hot-sauce manufacture and by novelty products. The extract business is the commercially significant part and none of it reaches a domestic kitchen as a spice.

Reasonable evidenceSources: Handbook of Herbs and Spices

Claims we do not accept at face value

  • The Carolina Reaper is the hottest pepper in the world.

    popular but unsupported

    True from 2013 and not since 2023, when Pepper X — bred by the same person — took the record. The claim is still printed on packaging and repeated widely, which is the same pattern ghost pepper shows: a record attaches to a pepper at the moment it becomes famous and outlives the fact.

  • A Carolina Reaper is 2.2 million Scoville units.

    contested

    That figure is the highest assayed sample rather than a typical pod. Published averages sit closer to 1.6 million, growing conditions move the result substantially, and pods from one plant differ from each other. Quoting a peak measurement as a property of the fruit is the false precision this dataset exists to avoid — and the Scoville scale itself was a human dilution panel devised in 1912, retrofitted to chromatography results at concentrations no panel could ever have scored.

Culture

Recorded by tradition rather than merged into one narrative — these are genuinely different practices.

Hot-sauce and extract industry

Its actual home. Reaper is grown commercially to be turned into sauces, extracts and snack seasoning, where the selling point is the name and the number rather than any flavour. It is one of very few entries in this dataset whose primary market is manufacturing rather than cooking.

Reasonable evidenceSources: Handbook of Herbs and Spices
  • In commercial hot sauces and extracts
  • Snack and crisp seasoning

Competitive eating and novelty

The context most people meet it in, and one worth naming rather than pretending away: eating challenges, dares and filmed reactions. SpiceHQ records this as a use of the pepper and takes no position on it, holding no clinical source on capsaicin at these concentrations — which means it can neither responsibly encourage the practice nor issue a warning about it, and says so instead of doing either.

Editorial judgementRecorded as an observation about how the pepper is used. The refusal to editorialise is itself the editorial position, and it follows from the evidence rules rather than from squeamishness.
  • Eating challenges
  • Novelty products and dares
Traditional medicinal context:

None. Carolina Reaper is fifteen years old and has no traditional-medicine record of any kind, which is worth stating explicitly because every other chilli in this dataset does.

Traditional practiceThe absence is the fact. Chillies generally carry long traditional records; a cultivar released in 2013 cannot.
