Mole is not a sauce — it is a practice
The word mole comes from the Nahuatl molli — a general term for sauce. But Oaxacan mole is better understood as a culinary tradition and a practice of patience. The seven canonical moles of Oaxaca (negro, rojo, coloradito, amarillo, verde, chichilo, manchamanteles) each require dozens of ingredients and hours of preparation.
Mole negro: the pinnacle
Mole negro is Oaxaca's most complex mole — typically 30+ ingredients including multiple dried chiles, chocolate, charred tortillas, avocado leaves, and spices. The preparation involves toasting, charring, grinding, and long-simmering over hours. Each family and cook has a distinct version passed across generations.
Chocolate's Mesoamerican origin
Cacao was domesticated in Mesoamerica. In Oaxacan cuisine, chocolate functions as a savory flavoring agent — adding depth, bitterness, and body to sauces. The Aztec emperor Moctezuma reportedly drank 50 cups of xocolātl per day. Oaxacan chocolate is still ground on stone metates, often combined with cinnamon and almond.
