Cuitlacoche Guisado con Jitomate
Origin
Valley of Mexico and surrounding Altiplano — principally the states of Mexico, Tlaxcala, Puebla, and the Federal District (CDMX), wherever Zea mays var. maíz criollo grows in close proximity to seasonal rains that trigger Ustilago maydis infection. The guisado format is most deeply rooted in the milpa communities of the Basin of Mexico, where the fungus has been harvested at the swollen, ink-filled stage since at least the Aztec period.
Description
A classic Central Mexican preparation of cuitlacoche — the ink-dark corn fungus (Ustilago maydis) prized since pre-Hispanic times — cooked down with ripe tomato, serrano chiles, and finished with epazote. The result is deeply savory, earthy, and faintly smoky, with a moist consistency that makes it ideal as a taco filling, quesadilla stuffing, or a side alongside eggs or grilled meat. Diana Kennedy's version is unfussy: the fungus does the work once heat and aromatics unlock its character.
The Thread
Flavour Context
Cuitlacoche carries a dense, mushroom-adjacent earthiness with an undercurrent of sweet corn that survives the cooking — the two identities never fully separate. Heat drives off excess moisture and concentrates the umami, while the tomato (jitomate bola or roma, Solanum lycopersicum) contributes brightness that keeps the dish from becoming oppressive. Epazote (Dysphania ambrosioides) cuts through at the finish with a sharp, resinous note that is the aromatic signature of every honest version.
