Chile costeño amarillo: a key ingredient of yellow mole

What is it?

Chile costeño amarillo is a regional dried chilli of the Costa Chica of Oaxaca, an essential ingredient of mole amarillo and of chichilo, two of the seven traditional Oaxacan moles. It is elongated and pointed, measuring between 5 and 8 cm, and is distinguished by its golden or amber yellow colour. It belongs to the species Capsicum annuum and is grown in small plots on the Oaxacan coast. Its heat is moderate (10,000-20,000 Scoville units). It brings a citrusy, fruity and herbal flavour with notes of tropical dried fruit. It is used mainly in mole amarillo, chichilo, yellow salsas and broths typical of Oaxacan cuisine. It is one of the chillies most defining of the indigenous and Afro-mestizo cuisine of the coastal region.

Origin and history

Chile costeño amarillo is one of the regional chillies most representative of the Costa Chica of Oaxaca. Its cultivation is of pre-Hispanic origin, traditionally grown in family milpas by Mixtec, Chatino and Afro-Mexican peoples. Larousse Cocina and the Encyclopaedic Dictionary of Mexican Gastronomy identify it as a key ingredient of Oaxacan yellow mole and of chichilo, alongside costeño rojo and chilhuacle amarillo. Oaxacan cooking, famous for its seven moles (negro, rojo, amarillo, verde, coloradito, manchamanteles and chichilo), has been inscribed on the Intangible Cultural Heritage of Humanity by UNESCO since 2010. CONABIO documents the importance of costeño amarillo as part of the heritage of native chillies of southern Mexico. SADER recognises it as a regional Oaxacan chilli with potential for a protected designation of origin. Its artisanal production in small coastal communities maintains traditional sun-drying techniques inherited over centuries.

Characteristic ingredients

Chile costeño amarillo is a Capsicum annuum grown in small family milpas on the Oaxacan coast. The fruits are harvested when ripe and sun-dried for several days until they take on a golden or amber yellow colour. The skin becomes smooth and crisp, and it measures between 5 and 8 cm with an elongated, pointed shape. Its heat is moderate (10,000-20,000 SHU) and it brings a distinctive citrusy flavour with notes of tropical dried fruit (dried mango, papaya) and a herbal hint. To use it, devein and deseed it, briefly toast on a comal and rehydrate in hot water for 10-15 minutes. Then blend with tomatillo, garlic and spices. It pairs very well with tomatillo, chilhuacle amarillo, hoja santa and miltomate to make mole amarillo. It is also used in chichilo (a dark mole with chilhuacle negro and chillies charred over coals) and in broths such as Oaxacan beef broth. Its intense yellow colour is the visual signature of mole amarillo.

Cultural significance

Chile costeño amarillo is a defining ingredient of Oaxacan cuisine, recognised as Intangible Cultural Heritage of Humanity by UNESCO since 2010. It is essential in two of the seven emblematic moles: mole amarillo (traditionally served with chicken or beef and maize dough) and chichilo (a funerary and festive mole). Its production and trade in Oaxacan markets such as Pinotepa Nacional, 20 de Noviembre and the Central de Abastos sustains the economy of indigenous Mixtec, Chatino and Afro-Mexican communities of the Costa Chica. SADER and CONABIO highlight its genetic value as part of the heritage of native chillies. In contemporary cooking, traditional cooks such as Abigail Mendoza (Tlamanalli) and chefs such as Alejandro Ruiz (Casa Oaxaca) keep it in their menus. Preserving costeño amarillo and chilhuacle is a banner of movements defending Oaxacan food biodiversity against the pressure of cheaper industrial chillies.

Frequently asked questions

What is the difference between chile costeño amarillo and chilhuacle amarillo?

Both are dried yellow Oaxacan chillies, but they come from distinct varieties and different regions of Oaxaca. Costeño amarillo is elongated, hot (10,000-20,000 SHU) and grown on the Costa Chica. Chilhuacle amarillo has a lantern shape, is less hot (1,000-2,500 SHU) and is grown exclusively in the Canada de Cuicatlan. The two are combined in mole amarillo, where chilhuacle brings body and costeño brings heat.

What does chile costeño amarillo taste like?

It brings a citrusy, fruity flavour with notes of tropical dried fruit (dried mango, papaya), a herbal hint and a touch of sweetness. Its heat is moderate (10,000-20,000 Scoville units), more intense than guajillo. When briefly toasted it develops aromas of dried fruit and honey, perfect for yellow moles and citrusy salsas.

What is chile costeño amarillo used for?

It is the base of Oaxacan mole amarillo (one of the seven traditional moles), of chichilo and of coastal yellow salsas. It is combined with chilhuacle amarillo, tomatillo, hoja santa, maize dough and cumin to prepare mole amarillo, traditionally served with chicken, beef or pork and masa dumplings (chochoyotes). It is also used in fish broths of the Oaxacan coast.

Where does chile costeño amarillo come from?

It is native to the Costa Chica of Oaxaca, where it is traditionally grown in small family milpas by indigenous Mixtec, Chatino and Afro-Mexican communities. SADER recognises it as a regional Oaxacan chilli with potential for a protected designation of origin. It forms part of the heritage of native Mexican chillies documented by CONABIO and is a defining ingredient of mole amarillo, an emblematic dish of Oaxacan cuisine recognised by UNESCO.
