New Mexican Chile: The Defining Ingredient

The chile pepper was cultivated by Pueblo people of the Rio Grande valley long before Spanish contact. The Spanish Colonial settlers adopted it, and by the 18th century it was grown in kitchen gardens from Santa Fe to Taos. The first registered New Mexican chile variety — New Mexico No. 9 — was developed by Dr. Fabian Garcia at New Mexico State University in 1907, beginning the scientific breeding programme that produced the famous Hatch chile varieties.

New Mexican chile — the fresh or dried pod of Capsicum annuum varieties grown in New Mexico's Hatch Valley, Chimayó, and other high-altitude river valleys — is the single ingredient that defines New Mexican cuisine and distinguishes it from every adjacent culinary tradition. Its specific character (earthy, complex, with a range of heat that varies by variety and ripeness) is produced by the combination of New Mexico's high altitude, desert sunlight intensity, and the specific soil of its river valleys. New Mexican chile grown elsewhere tastes different — not categorically wrong, but detectably different from the soil-specific original.

New Mexican chile sits in a specific position on the flavour map: earthy depth and fruity sweetness from the dried red, bright grassiness and fresh heat from the green. Neither is interchangeable with the other in a recipe that specifies one — they are different preparations from the same plant at different stages of its life cycle.
