Calabrian chilli

• peperoncino

  Italian

  The general Italian word for chilli, not a Calabrian one. A jar labelled peperoncino may hold anything from mild flakes to a fiery paste, and the region is what narrows it.

• diavolicchio

  Italian

  Literally "little devil" — a Calabrian regional name, and also used for particular local varieties.

• bomba calabrese

  Italian

  A prepared chilli-and-vegetable paste rather than the chilli itself. Recipes calling for "Calabrian chilli paste" usually mean this, and it brings oil, salt and other vegetables with it.

Fruity and rounded with a clean building heat and very little bitterness. It is hot enough to be a chilli rather than a seasoning, unlike Espelette or Aleppo, and fruity enough to be used generously.

Fruity and sweet with a sun-dried warmth, and noticeably more aromatic than generic crushed chilli. The oil-packed and fermented forms add a tang the dried flakes do not have.

Bright to deep red as dried flakes, with plenty of visible seed. Oil-packed chillies are darker and glossy; the paste is a deep brick red.

Coarse and seedy as flakes; soft and yielding in oil; smooth and spreadable as paste. The three forms differ more in texture than in flavour, and the texture is usually why a recipe names one.

• Capsaicin — The pungency, and unusually available in the oil-packed forms because it is already in solution.
• Carotenoids — The red colour, which bleeds readily into oil and is why chilli oil made with these turns a strong red.

Put it in the oil, and put it in early. Capsaicin and the red carotenoids are both fat-soluble, so flakes warmed in olive oil at the start of a dish distribute heat and colour through everything that follows in a way that adding them at the end cannot — this is the single technique that distinguishes an Italian chilli dish from a dish with chilli sprinkled on it. Keep the oil warm rather than hot: these flakes carry seed and sugars and scorch into bitterness quickly. Where the heat has to be controllable, infuse a whole dried chilli and lift it out. And read the jar before substituting: the oil-packed and fermented forms bring salt, acidity and often other vegetables, so a recipe built on bomba is not a recipe built on flakes with extra heat. Judge freshness by smell rather than by heat, because the fruitiness that makes this worth buying fades long before the burn does.

The working chilli of southern Italian cooking. Flakes go into warm olive oil at the start of a pasta sauce — aglio e olio, arrabbiata, puttanesca — and with seafood, greens, beans and roast vegetables. Whole dried chillies infuse olio santo. The oil-packed and paste forms go onto bread and pizza, into dressings and sauces, and into the preserved larder that includes ’nduja. It suits garlic, olive oil, tomato, anchovy, broccoli, cime di rapa, beans, pork and any firm white fish, and it belongs with oregano, fennel seed and parsley rather than with the cumin-led register of the Mexican chillies here.

• frying — The standard Italian move: flakes go into warm olive oil at the start, where both the heat and the colour move into the fat and distribute through the dish. Capsaicin is fat-soluble, so this does far more than adding flakes at the end.
• infusing — Whole dried chillies steeped in warm oil give a gentler, more even heat and can be removed. This is how olio santo is made and how a cook controls a dish that must not be too hot.
• grinding — Flakes are already crushed with the seed. Grinding finer makes the heat more uniform and loses the flecked look that Italian dishes generally want.

Smell the flakes before tasting them. Good Calabrian chilli smells distinctly fruity and sun-dried; an old jar smells of dust and still tastes hot. Heat is the last thing to go and therefore the worst thing to judge by.

• Colour faded from bright red towards brown.
• Dusty smell with no fruitiness, even where the heat is unchanged.
• Webbing, fine powder or small holes in dried flakes, meaning pantry insects.
• For pastes and oil-packed jars: mould at the surface, or material sitting above the oil.

The useful question here is not whole versus ground but which of three products to buy, and the answer follows the dish rather than any general preference. Dried flakes are the everyday choice: cheap, long-keeping, and right for blooming in oil at the start of a pasta sauce. Whole dried chillies are worth having where the heat must be controllable, because a chilli infused into warm oil can be lifted out and flakes cannot. The oil-packed and paste forms are a different purchase entirely — they carry salt, oil, acidity and often other vegetables, they belong in the fridge once opened, and a recipe from a restaurant kitchen naming "Calabrian chilli" usually means one of them. Buying flakes to make a dish that wanted bomba produces something thinner and under-seasoned, and the reverse over-salts it.

• Decide which of the three products the recipe wants before buying — flakes, oil-packed or paste — because they are not substitutes.
• For flakes: bright red rather than brown, and a fruity smell rather than a dusty one.
• For oil-packed and paste: check the ingredients, since many jars contain other vegetables, vinegar and a substantial salt load.
• Treat "Calabrian" as a description rather than a controlled term — unlike Espelette, nothing protects it.
• Buy flakes in small opaque jars; the colour and fruitiness fade well before the heat does.

No appellation and no formal grading scale, which distinguishes it sharply from Espelette. What varies commercially is the form, the variety mix and whether the material is genuinely Calabrian, and none of that is certified. Price differences therefore reflect brand and form more than any verifiable quality tier.

Solanaceae

A compact annual bearing small tapered or rounded fruit, generally three to six centimetres, ripening bright red. Traditionally strung into garlands and hung to dry on balconies and house walls across Calabria, which is where the familiar image of the spice comes from.

The Americas, as with all Capsicum, reaching southern Italy in the sixteenth century and naturalising into Calabrian cooking so thoroughly that it now reads as indigenous. Calabria took to chilli in a way northern Italy never did, and the north–south divide in Italian spicing largely tracks it.

• IT (Calabria) — major producer. The named source, though "Calabrian chilli" on an export label is not a protected term and is not always Calabrian.
• IT (Basilicata and Puglia) — notable producer

Picked ripe and red in late summer, over several passes. Fruit destined for oil-packing and paste is used fresh; fruit for flakes is strung and dried.

1. Sun drying, for flakes — Fruit strung into garlands and sun-dried, then crushed with the seed.Why: The dry form, and the one a recipe naming "Calabrian chilli flakes" means.
2. Packing in oil — Fresh chillies, whole or halved and sometimes stuffed, packed in oil and often lightly salted or vinegared first.Why: Preservation, and a product with a soft texture and a carrying oil that dried flakes cannot substitute for.
3. Fermenting and pasting — Chillies salted and fermented, then blended — alone or with other vegetables — into a paste sold as bomba or crema di peperoncino.Why: A third product entirely, bringing salt, acidity and ferment character alongside the heat.

No appellation and no formal grading scale. "Calabrian" on a jar is a description rather than a controlled term, which is a genuine difference from Espelette and worth knowing before paying a premium for it.

A mixture of smallholder and commercial growing, with a substantial domestic and household component — chillies strung on a balcony are still a normal sight. There is no appellation controlling the name, so commercial supply is looser than for a protected spice.

Hot dry Mediterranean summers with reliable sun for drying, which is what makes the traditional string-drying practical here and not in the Basque country.

Chilli arrived in southern Italy in the sixteenth century and was taken up in Calabria with an enthusiasm that has no parallel further north — it was cheap, it grew locally, and in a poor region it seasoned food that black pepper could not have afforded to. The result is the sharpest internal divide in Italian spicing: a southern cooking built on peperoncino and a northern one that barely uses it. The oil-packed and fermented forms are preserving traditions from the same economy, turning a seasonal glut into a larder that lasts the year.

A substantial domestic Italian trade and a growing export one, particularly in oil-packed and paste products, which travel better and carry more margin than dried flakes. "Calabrian" is not a protected term on an export label, so the name travels more freely than the crop does.

No distinct traditional medicinal tradition is recorded for the Calabrian chilli as such, beyond the general folk attributions attached to chilli everywhere. Held as an absence rather than an omission.
