Chiltepín chilli: what it is, heat, uses and substitutes

What is it?

The chiltepín chilli is one of the oldest and hottest wild chillies of Mexico, considered by many botanists to be the ancestral chilli or 'mother chilli' from which numerous modern varieties descend. It is very small (3-5 mm), round like a pellet, an intense red when ripe, and grows on wild plants in mountainous areas and dry tropical forests. It belongs to the species Capsicum annuum variety glabriusculum. It is gathered mainly in Sonora, Chihuahua and Sinaloa, where it is considered a regional symbol. Its heat is very high (50,000-100,000 Scoville units), but fleeting. It provides a fresh, herbal, slightly fruity flavour, and is used in table salsas, broths, pickles, hot powders and as a seasoning over tacos, beans and grilled meat.

Origin and history

The chiltepín is considered by archaeobotanists and by the University of Arizona to be one of the ancestral wild forms of Capsicum annuum, present in the American continent for at least 8,000 years. Its wild distribution runs from the south-west of the United States to South America, and in Mexico it is concentrated in the Sierra Madre Occidental. The Yaqui, Mayo and Rarámuri cultures have gathered it since pre-Hispanic times as a central part of their diet. The Florentine Codex mentions the 'chiltecpin', and the codices of New Spain identify it as one of the oldest and hottest chillies. CONABIO highlights its genetic value as a plant genetic resource for improving modern varieties. SADER recognises it as a wild Sonoran product with a denomination of origin in process. In 1999 the Quitovac National Forest Reserve was created in Sonora partly to protect its wild populations. Today sustainable gathering and semi-technified cultivation projects are carried out.

Characteristic ingredients

The chiltepín is a wild, perennial chilli that grows beneath mother trees such as the mesquite or the wild fig, in habitats with partial shade and rich soils. The seeds are dispersed by birds (hence the Nahuatl name 'chiltecpin', flea chilli, because of the seedlings that sprout where the birds land). The fruits are spherical, 3-5 mm, and are harvested by hand one by one as they ripen, which explains their high price in the market. The distinction from the piquín lies in the shape: the chiltepín is round and the piquín is oval or oblong, although botanically they are the same variety. Its heat (50,000-100,000 SHU) is very intense but short, and does not accumulate. It is used fresh - crushed over tacos and beans - or dried - toasted on a comal and crushed in a mortar for table powder. It is boiled whole in broths such as the Sonoran cocido and used for fresh salsas with tomato and garlic. It pairs very well with lime, salt and avocado.

Cultural significance

The chiltepín chilli is an identity symbol of northern Mexico, especially Sonora, where it is considered 'red gold'. It forms part of the traditional Mexican cuisine inscribed by UNESCO as Intangible Cultural Heritage. It is an essential ingredient of Sonoran dishes such as cocido, machaca, salsas for grilled meat and frijoles rancheros. Its wild gathering by ranching families and indigenous communities (Yaqui, Mayo, Ópata, Seri) is a key economic activity during the months of August to November, at the height of the rainy season. SADER and CONABIO promote sustainable-management programmes to avoid overexploitation. Its genetic value is strategic: as a wild form of Capsicum annuum, it retains traits lost in commercial varieties. Sonora holds the Chiltepín Festival each year, and in Baviácora there is the Sonoran Chiltepín Festival, which brings together producers, cooks and scientists.

Frequently asked questions

What is the difference between chiltepín and piquín?

Botanically they are the same variety (Capsicum annuum var. glabriusculum) and many use them as synonyms. The most common difference is the shape: the chiltepín is spherical, like a pellet, while the piquín is oval or oblong. By region, chiltepín is associated with the north-west (Sonora, Chihuahua) and piquín with the north-east and centre. The chiltepín is usually a little hotter (50,000-100,000 SHU vs 30,000-60,000 SHU).

What does the chiltepín chilli taste like?

It has a herbal, fresh and clean flavour, with mild fruity notes and a very high but fleeting heat (50,000-100,000 Scoville units). The heat arrives quickly and fades quickly, without accumulating, so although it is intense, it does not dominate the palate as much as the habanero. Fresh it is somewhat reminiscent of green tomato with chilli; dried it provides toasted woodfire notes.

How is the chiltepín used in Sonoran cuisine?

It is crushed fresh over frijoles puercos, machaca and grilled meat; crushed dry in a mortar with salt to make table powder; boiled whole in broths such as the Sonoran cocido; and used for salsas with tomato, garlic and salt. It is also made into a Sinaloa salsa with tomato and vinegar, and served over tacos and seafood. In cantinas it is crushed over beer to make northern micheladas.

Where does the chiltepín chilli come from?

It is native to the American continent and is considered one of the ancestral chillies. In Mexico it grows wild in the Sierra Madre Occidental, especially in Sonora, Chihuahua and Sinaloa. The Yaqui, Mayo, Ópata and Seri peoples have gathered it for centuries. Today Sonora is the main chiltepín-producing state, with a denomination of origin in process and a very strong cultural identity around its gathering.
