Chile piquin: the wild Mexican chilli

What is it?

Chile piquin is one of the oldest and wildest chillies of Mexico. It is small, just 1-2 cm, oval or round and a deep red when ripe. It belongs to the species Capsicum annuum, variety glabriusculum, considered the ancestral wild form of many modern cultivated chillies. It grows wild or semi-cultivated in Tamaulipas, Nuevo Leon, San Luis Potosi and Veracruz, where it is gathered from plants growing under other trees. Its heat is very high (30,000-60,000 Scoville units) and its flavour is sharp, fruity and short-lived. It is used for chilli powder for the table, table salsas, pickles and, above all, to spice up fresh fruit, jicama, orange and cucumber, one of the most widespread food traditions in Mexico.

Origin and history

Chile piquin is one of the oldest chillies of the American continent. Archaeobotanical studies place its origin in a zone that stretches from northern Mexico to South America and consider it the wild ancestral form from which many modern chillies were domesticated. Indigenous peoples of north-eastern and central Mexico gathered it from wild plants growing under mesquites and huizaches, where it seeds itself thanks to birds that disperse its seeds. Fray Bernardino de Sahagún mentions in the Florentine Codex the 'chiltecpin', 'flea chilli', referring to this tiny chilli. Larousse Cocina and CONABIO highlight its importance as a traditional wild resource with cultural, food and economic value. SADER recognises its harvest in Tamaulipas as a significant rural activity, with plans to protect sustainable gathering and promote semi-technified cultivation to meet growing demand.

Characteristic ingredients

Piquin is a wild and semi-cultivated chilli: most of the harvest in Mexico comes from gathering wild plants growing at the edges of dry tropical forests and scrubland. Its fruits are very small (1-2 cm), oval, round or bullet-shaped, and ripen from green to deep red. The plant is perennial and very branched. Piquin is sold fresh, dried whole, as a powder or crushed. Its heat is high (30,000-60,000 SHU) but less persistent than that of the habanero, so it is considered a 'quick heat'. Its flavour is direct, fruity, slightly citrusy when fresh and herbal-toasted when dried. To use it, the dried chillies are crushed in a mortar or processor together with salt to make piquin powder, the base of the famous 'chilli powders' for fruit. It is also boiled whole in table salsas and pickles, and added to spicy oils. It is usually combined with lime and salt on fresh fruit.

Cultural significance

Chile piquin is a fundamental part of popular Mexican food culture. It is part of the traditional repertoire recognised by UNESCO as Intangible Cultural Heritage. Its consumption is widespread throughout the country and especially in the north-east, where it is an essential ingredient of the chilli powder used on fruit and ice lollies. Its gathering sustains the economy of rural communities in Tamaulipas, Nuevo Leon, San Luis Potosi and Veracruz, mainly women and families who harvest it by hand during the season (August-November). SADER and CONABIO have driven sustainable gathering and semi-cultivation projects to avoid overexploiting wild populations. Piquin is also the ancestral botanical origin of many modern cultivated varieties, so its conservation has genetic value for agriculture. Commercial brands such as Tajin and Lucas Limon include piquin in their chilli powders, exported to more than 30 countries.

Frequently asked questions

What is the difference between chile piquin and chile chiltepin?

Both are small wild chillies of the same species and variety (Capsicum annuum var. glabriusculum) and are often used as synonyms. They are usually told apart by shape: piquin is more elongated or oval and chiltepin is spherical, like a small pellet. Chiltepin is gathered above all in Sonora and Chihuahua and is somewhat hotter (50,000-100,000 SHU), while piquin is associated with the north-east and the Gulf.

What does chile piquin taste like?

It has a fruity, herbal and slightly citrusy flavour, with sharp, quick heat (30,000-60,000 Scoville units). Fresh piquin recalls the flavour of green tomato mixed with chilli, and dried piquin brings toasted notes and a natural smoky finish. The heat is felt mainly on the tip of the tongue and fades faster than that of the habanero, which is why it is considered a quick, clean heat.

What is chile piquin used for?

Its most popular use is as chilli powder for fresh fruit (jicama, orange, mango, watermelon, cucumber) and for ice lollies, micheladas and snacks. It is also used whole for spicy table salsas, pickles, infused oils and as a spicy garnish in aguas frescas and cocktails. In north-eastern cooking it is added to stews such as cabrito and grilled meats to bring heat without overpowering the underlying flavour.

Where does chile piquin come from?

It is native to the American continent, with a wild presence from northern Mexico to South America. In Mexico it is gathered mainly in Tamaulipas, Nuevo Leon, San Luis Potosi and Veracruz, where it grows wild or semi-cultivated. Its Nahuatl name 'chiltecpin' appears in colonial sources from the sixteenth century. It is considered one of the ancestral chillies from which many modern cultivated varieties descend.
