Güero chilli: what it is, taste, heat and substitutes

What is it?

The güero chilli is the general name given in Mexico to a group of fresh chillies of pale yellow, pale green or creamy colour. It is not a single variety, but a family of chillies with light tones that includes several regional cultivars such as the caribe, the caloro, the carricillo and other local güeros. It measures between 6 and 12 cm depending on the variety, has smooth skin and fleshy pulp, and is harvested when still young and yellow. It belongs to the species Capsicum annuum. It is grown mainly in Sinaloa, Nayarit, Sonora and the State of Mexico. Its heat is moderate (2,500-8,000 Scoville units), comparable to the jalapeño. It contributes a vegetal, slightly sweet and herbal flavour. It is used in broths such as fish broth, pickles, fresh salsas, Veracruz-style fish and dishes of the north and the Pacific coast.

Origin and history

The güero chilli encompasses several varieties grown in Mexico since colonial times, all with the common trait of being harvested young with yellow, pale-green or cream skin before ripening to red. The colonial sources mention various light-coloured chillies used in regional kitchens. Larousse Cocina and the Diccionario Enciclopédico de la Gastronomía Mexicana document the different regional cultivars: the caribe of the north (Sonora-Sinaloa), the caloro and the carricillo of the centre and west, the Yucatecan güero (xcatic), etc. SADER recognises it as a category of regional fresh chillies with production concentrated in the Pacific and Gulf states. CONABIO documents the diversity of these cultivars as part of the heritage of native Mexican chillies. Its historical use is linked to coastal cuisines: the güero chilli is an identity-bearing ingredient of Veracruz-style fish (19th century) and of the stuffed güero chilli in escabeche typical of Sinaloa.

Characteristic ingredients

Under the name 'güero chilli' several varieties of Capsicum annuum with pale yellow, pale green or cream skin are grouped. The most common in Mexican markets are: caribe (Sonora-Sinaloa, 8-12 cm, spicier), caloro (centre, 7-10 cm, moderate heat), carricillo (Pacific, elongated and spicy) and common güero (5-8 cm, mild). All share smooth skin, fleshy pulp and are harvested young with a light colour before ripening to red. Their heat is moderate (2,500-8,000 SHU). They contribute a vegetal, slightly sweet and herbal flavour, with less astringency than the jalapeño and more juiciness. To use them, they are lightly roasted on the comal or used raw. They are added whole to broths (fish broth, seafood soup) to provide heat without overdoing it, pickled with onion and vinegar (güero chillies in escabeche), stuffed in some regions of the north, and are an iconic ingredient of Veracruz-style fish, alongside olives, capers and tomato.

Cultural significance

The güero chilli forms part of the repertoire of traditional Mexican cuisine recognised by UNESCO as Intangible Cultural Heritage. It is an identity-bearing ingredient of the cuisine of the Pacific (Sinaloa, Nayarit, Sonora) and the Gulf (Veracruz), where it is used in emblematic seafood preparations such as Veracruz-style fish, seafood broth and pickled güero chillies. SADER reports Sinaloa as the main national producer, with significant exports to the United States. The commercial pickle industry with brands such as La Costeña and Herdez includes the güero chilli as one of its best-selling products. In Sinaloan coastal cuisine, the güero chilli stuffed with seafood in escabeche is a typical dish of regional festivities. In contemporary cooking, chefs of the Mexican Pacific such as Mariana Orozco have revived the güero chilli as a fresh ingredient for tiraditos and aguachiles, where it provides gentle heat with a fruity profile.
