Chile de árbol: what it is, heat and uses in salsas

What is it?

The chile de árbol is one of the hottest and most popular chillies in Mexican cuisine. It is thin, elongated (5-7 cm), an intense bright red, and is almost always sold dried. It belongs to the species Capsicum annuum (variety acuminatum) and is grown above all in Jalisco, Nayarit and Guerrero. Its heat is high (15,000-30,000 Scoville units), comparable to cayenne, and its flavour is direct, herbal and sharp. It is the base of chile de árbol salsa, salsa macha, hot oils, chilli-coated peanuts and many table salsas for tacos and antojitos. Its name (literally 'tree chilli') comes from the fact that the plants, woody, grow tall and resemble small trees, unlike most chillies, which are herbaceous.

Origin and history

The chile de árbol comes from a Mesoamerican lineage of Capsicum annuum cultivated since pre-Hispanic times. The plants are woodier and more durable than those of other chillies, which gave rise to its Spanish name. There are 19th-century records in Jalisco that already identify it as a regional export product. Larousse Cocina notes that the dried chile de árbol has become one of the most widely marketed dried chillies in the country, above all because of its use in the bottled-salsa industry and chilli-coated snacks. SADER includes it among the emblematic dried chillies of Mexico and reports Jalisco, Nayarit and Guerrero as the main producing states. In the region of Yahualica, Jalisco, the denomination of origin 'Chile de árbol Yahualica' is being promoted, applied for by local producers for the quality of the fruit grown in volcanic soils.

Characteristic ingredients

The chile de árbol is grown as a fresh green or red chilli, but is consumed almost exclusively dried. It has smooth, shiny and firm skin, and because of its slender shape it dries quickly in the sun (3-5 days). It measures between 5 and 7 cm and is sold whole, in flakes or as a powder. It should not be confused with the American cayenne (which is another variety of the same species) nor with the puya chillies, which are wider. To use it, it can be briefly fried whole in oil, lightly toasted on a comal or rehydrated in hot water to blend. Its high heat (15,000-30,000 SHU) makes it ideal when a sharp, clean heat is sought, without too much complexity. It pairs very well with tomatillo for a raw salsa, with sesame and peanut for salsa macha, with oil for crunchy chilli, and with tomato and vinegar for bottled salsas. In industry, it is exported dried and as a powder to many countries as 'Mexican red chile pepper'.

Cultural significance

The chile de árbol is one of the most recognisable chillies of the Jalisco agricultural landscape. Its production in municipalities such as Yahualica de González Gallo is a key economic activity and a source of regional pride, with annual festivals dedicated to the chilli and applications for a denomination of origin. It forms part of the traditional Mexican cuisine inscribed by UNESCO as Intangible Cultural Heritage. Salsa macha, originally from Veracruz and Oaxaca but popularised nationally, is based on chile de árbol with sesame and peanut, and has been enjoying a gastronomic boom since 2020 thanks to contemporary cooking. Brands such as Valentina and Tamazula, originally from Jalisco, use chile de árbol as the main ingredient of their bottled salsas, leaders in Mexico and exported to more than 50 countries. It is also a key ingredient of chilli-coated snacks (peanuts, crisps, fried snacks) and of the famous chamoy and chilli powders.
