History

Illustrated historical scene for Ají

Capsicum baccatum, commonly called ají chile, ají amarillo, or Peruvian ají, is one of the five fully domesticated species of Capsicum, native to the central Andes (principally modern-day Peru and Bolivia) and domesticated from wild populations around 2500 BCE—archaeological evidence from Huaca Prieta in Peru confirms this ancient cultivation. Carl Linnaeus described it in 1767. The epithet baccatum means berry-bearing.

The species is the foundational chile of Peruvian cuisine, where ají amarillo (orange-yellow pods) is essential to dishes like papa a la huancaína and ají de gallina. Plants are tall and sprawling at 1.5-2 meters with distinctive cream-yellow spots at the base of the five petals of the flowers (a diagnostic feature distinguishing the species from C. annuum, C. chinense, and C. frutescens).

Fruit pods are typically 10-15 cm long, tapering, in bright orange, yellow, or red, with a distinctive fruity citrusy flavor and moderate heat (30,000-50,000 Scoville). Increasingly available in American garden seed catalogs as Peruvian cuisine grows in popularity. Cultivars include 'Lemon Drop', 'Aji Amarillo', 'Aji Limo', and 'Bishop's Crown'.

Its heritage stretches back four thousand years through Andean kitchens and ceremonial meals, one of the oldest domesticated chilis on earth. To grow it is to taste a long line of Andean cooks, gardeners, and traders connecting fields to plates.
