Aji Amarillo

The Aji Amarillo is Peru's national chilli - a long, tapered Capsicum baccatum that ripens to brilliant orange-yellow despite its name (amarillo means yellow). It's the foundational pepper of Peruvian cuisine, contributing to dishes like ají de gallina, papa a la huancaína, and causa rellena. The flavour is unmistakably Andean: fruity, slightly berry-like, with a warm complex heat that builds gradually rather than punching.

History & lineage

The Aji Amarillo is one of the oldest cultivated chillies in the Americas. Archaeological evidence places Capsicum baccatum cultivation in the Peruvian Andes back at least 7,500 years, with seeds and pod fragments recovered from archaeological sites across coastal and highland Peru. The Aji Amarillo represents the modern descendant of this ancient cultivation tradition, refined through millennia of Andean agriculture.

In Peruvian cuisine, the Aji Amarillo holds a position roughly equivalent to that of the Habanero in Yucatán or the Scotch Bonnet in Jamaica - it's not just a chilli, but a defining flavour signature. Pre-Columbian civilisations including the Moche, the Nazca, and ultimately the Inca all incorporated baccatum varieties into their cooking, and the Spanish chroniclers of the 16th century recorded "ají" as the everyday word for chilli throughout the Andean world (a Quechua-derived term that displaced the Mexican "chile" across South American Spanish).

When dried, the Aji Amarillo becomes the Aji Mirasol - the name shifting because the dried pods, hung to dry, appear to "look at the sun" (mira-sol). Both forms are central to traditional cooking: the fresh paste for the bright, vibrant dishes of coastal Peruvian cuisine; the dried form for the deeper, richer Andean stews and slow-cooked preparations.

The global rise of Peruvian cuisine - led by chefs like Gastón Acurio in the 2000s and 2010s - has brought the Aji Amarillo to international prominence. Where it was once a regional ingredient barely known outside South America, the variety is now stocked by speciality grocers across Europe, North America, and Asia, and Peruvian-style cooking has become one of the fastest-growing global cuisine trends.

Culinary uses

Essential to Peruvian cooking, used as fresh paste (pasta de ají amarillo), dried (then called ají mirasol), or processed into the bottled pastes that define modern Peruvian home cooking. Forms the base of countless traditional dishes including causa, ají de gallina, ocopa, and tiraditos. Pairs beautifully with seafood, chicken, and potato-based dishes. Now widely available in UK supermarkets serving Peruvian cuisine.
