Guajillo

The Guajillo is the dried form of the Mirasol chilli - the fresh-form name shifting to "guajillo" once the pods are dried, in the same pattern as Poblano-becoming-Ancho or Chilaca-becoming-Pasilla. Spanish "guajillo" derives from "guaje", a type of Mexican tree whose long pods bear visual resemblance to the dried chillies. The variety has been cultivated across central Mexico for centuries and remains one of the country's most-produced dried chillies. In Mexican cuisine, the Guajillo holds a position alongside the Ancho and the Pasilla as one of the foundational dried chillies of mole production and broader Mexican cooking. Where the Ancho contributes sweetness and fruit, and the Pasilla brings smoky earthiness, the Guajillo provides the bright, slightly tangy berry notes and clean medium heat that round out traditional mole sauces. The combination of all three - "the holy trinity of mole chillies" - is essential to authentic mole poblano and many regional mole variations. Beyond mole, Guajillo features in countless Mexican preparations: in red enchilada sauce (the foundation chilli for traditional rojo enchilada preparation), in adobo marinades for slow-cooked meats, in tamale fillings, in salsas roja, and as a base for chile-flavoured beverages and savoury sauces. The variety is genuinely versatile - reasonably mild (typically 2,500-5,000 SHU), with deep red colour and balanced flavour that suits a broad range of applications. The variety has become widely accessible internationally through the global spread of Mexican cuisine. UK supermarkets reliably stock dried Guajillo in their Mexican-cuisine sections, and the chilli has become standard issue for British home cooks attempting authentic Mexican preparation. The fresh form (Mirasol) is much less commonly encountered outside Mexico - reflecting the variety's primary identity as a dried-chilli rather than fresh-cooking ingredient.
