Camarones en Chileajo (Prawns in Oaxacan Chilli-Garlic Sauce)

History & Origin

Chileajo is one of the most representative sauces of Oaxaca, especially from the Isthmus of Tehuantepec, where Zapotec and Huave cultures have an extraordinary culinary presence. Its name describes the sauce perfectly: "chile" plus "ajo" (garlic) - the two ingredients that give it its character. Simple in essence, chileajo has a complexity built on the process of toasting and charring the ingredients. In the Isthmus, the sea is a fundamental source of protein, and fresh prawns from the Gulf of Tehuantepec are of exceptional quality. The Tehuana women - known for their colourful dress and central role in social and economic life - are the custodians of this recipe. Historically they prepared it with dried prawns, which keep better in the warm regional climate, but the version with fresh prawns has become equally popular. What makes Oaxacan chileajo special is its technique: chillies are toasted almost to burning, garlic is roasted unpeeled, tomatoes are also roasted, and everything is ground with spices such as cumin and dried leaf oregano. The result is a deep red sauce with smoky nuances and a concentrated flavour that perfectly envelops the prawns.
