Cayenne pepper

• lal mirch powder

  Hindi

  Indian recipes calling for red chilli powder rarely mean cayenne specifically; the heat of what is sold varies widely by region.

• cayena

  Spanish

• poivre de Cayenne

  French

  Named as a pepper but unrelated to black pepper — it is a ground chilli.

Sharp, clean heat with a light fruitiness behind it and little complexity. It contributes pungency more or less neutrally, which is exactly why it is the standard way to raise heat without altering flavour direction.

Modest and slightly fruity; cayenne is not bought for aroma and does not have much.

Bright to deep red powder, generally flecked with paler seed fragments.

A fine powder that disperses easily and is very easy to over-add.

• Capsaicin — The dominant pungent compound; binds the TRPV1 receptor, the same receptor activated by heat, which is why the sensation registers as burning.
• Capsanthin — Red colour, though present at lower levels than in paprika cultivars.

Add to fat rather than to a dry pan, and add it early enough to distribute. Add less than you think and taste, since capsaicin does not cook off and there is no way to remove heat once it is in.

Used wherever heat is wanted without changing the flavour direction of a dish: Cajun and Creole cooking, hot sauces, spice rubs, curries, and as a small corrective addition to sauces, eggs and cheese dishes. Because it is comparatively neutral in flavour, it is the most controllable way to raise heat.

• blooming — Capsaicin is fat-soluble, so cayenne added to hot fat distributes heat evenly through a dish. Added dry at the end it gives an uneven, patchy burn.
• boiling — Capsaicin is heat-stable and does not cook off. A dish will not become milder with longer simmering, which is a common and expensive misconception.
• frying — Burns quickly in a dry hot pan and turns acrid.

Judge by colour: bright red is fresh, brown-red is old. Do not judge by heat, which persists long after everything else has gone.

• Browned colour
• Dusty smell
• Caking

• Photodegradation of the red carotenoids, browning the colour
• Loss of the modest aroma fraction
• Capsaicin itself is stable, so old cayenne stays hot while looking and smelling tired

Ground is fine here. Cayenne is bought for pungency, and capsaicin is stable and non-volatile, so pre-ground cayenne loses very little of what you actually want from it. This is the clearest counter-example to the general rule that whole spices are better.

• A stated Scoville figure or heat level, since "cayenne pepper" on a label is a trade description rather than a specification.
• Bright red colour rather than brown.
• A named chilli variety where the supplier offers one.

Traded on measured capsaicinoid content converted to Scoville Heat Units, plus colour and cleanliness. Retail packs rarely carry the figure, which is the main practical difficulty in buying cayenne deliberately.

Solanaceae

An annual bearing slender, elongated fruits that ripen to red and are dried whole.

The Americas, where Capsicum annuum was domesticated.

• India — major producer. The largest producer of dried chillies overall.
• China — major producer
• Mexico — notable producer

Fruit is picked fully ripe and red, then dried whole.

1. Ripening and picking — Fruits are left to colour fully before picking.
2. Drying — Sun-dried or mechanically dried whole.
3. Milling — Dried pods are milled whole, including seeds and placenta.Why: Retaining the placental tissue is what makes the product pungent; removing it is what makes paprika.

Traded on measured capsaicinoid content expressed in Scoville Heat Units, determined by HPLC and converted, together with colour and cleanliness specifications.

Subject to the same colourant adulteration history as paprika, including the Sudan dye incidents, together with bulking using other ground plant material.

Grown as an annual field crop; pungency is affected by cultivar, but also meaningfully by growing conditions, with water stress tending to increase capsaicinoid content.

Warm conditions with a long ripening and drying season.

Chillies were domesticated in the Americas and carried worldwide after 1492, and were adopted with remarkable speed across South Asia, Southeast Asia, Africa and China — in many cases displacing or supplementing the local pungent spices, such as black pepper in India, within a century or two.

1. Pre-Columbian · Mesoamerica and South America

   Capsicum species are domesticated in the Americas and are in long-established use.

2. Post-1492 · Global

   Chillies are carried to Europe, Africa and Asia through Portuguese and Spanish trade routes.

   One of the fastest and most complete global adoptions of any food plant.

Dried chilli is now among the highest-volume spice commodities in world trade, with India and China dominating production.
