Huitlacoche, also known as corn smut, is a fungus that grows on ears of corn. It is considered a delicacy in Mexican cuisine and has been eaten in Mexico for centuries. Huitlacoche has an earthy, mushroom-like flavor and is used in dishes like quesadillas, tamales, and soups. It is rich in nutrients like protein, minerals, and dietary fiber. Though viewed as a crop disease in most countries, huitlacoche is prized in Mexican cooking for its unique culinary qualities.
What is Huitlacoche?
Huitlacoche, sometimes spelled cuitlacoche, is a fungus that grows on ears of corn. Its scientific name is Ustilago maydis. It is also referred to as corn smut or Mexican truffle. Huitlacoche is considered a disease in most countries, where it can ruin commercial corn crops. However, in Mexico it has been traditionally harvested and eaten as a food. Huitlacoche has been consumed in Mexican cuisine since pre-Hispanic times.
When the fungus attacks the corn, it causes the corn kernels to become swollen and take on enlarged, bulbous shapes. The corn kernels transform into huitlacoche galls that are blue-gray or blackish in color. Inside, the galls have a soft, mushy texture that can be grayish-brown, yellow, or olive-green. Huitlacoche has an earthy aroma reminiscent of mushrooms. Its flavor is subtly sweet and umami.
Where Does Huitlacoche Come From?
Huitlacoche is native to Mexico and Central America. It has been eaten in the region for hundreds of years, dating back to the ancient Aztec and Mayan civilizations. The Nahuatl word “cuitlacochin” meant “corn smut” and is the origin of the modern Spanish name. However, the delicacy has gained popularity more recently in the rest of the world.
The fungus that causes huitlacoche is Ustilago maydis. It is a plant pathogen that infects corn specifically. Ustilago maydis spreads through spores that travel through the air and infect corn plants. Hot and humid environments are ideal for its growth. The fungus directs the corn plant to create the swollen galls that become huitlacoche.
While it damages corn crops, Ustilago maydis has a complex lifecycle. It can live symbiotically with the corn plants, which allows both the fungus and the plant to reproduce. The fungus cannot complete its lifecycle or reproduce without the corn host. This close relationship developed over thousands of years of evolution between the two organisms.
How is Huitlacoche Harvested?
In Mexico, many farmers intentionally cultivate corn for huitlacoche production rather than harvest a full corn crop. They create conditions that help the fungus thrive and infect the corn. To encourage infection, farmers plant their corn crops densely, irrigate frequently, and add fertilizer. The fungus spreads rapidly under these conditions.
Farmers check their corn fields daily during growing season for signs of infection. Once huitlacoche galls appear on the ears of corn, they must be harvested quickly before the fungus matures and dries out. The ideal stage for harvest is when the galls are still soft, spongy, and dark in color. The infected ears of corn are removed by hand and the galls are cut off the cob.
Traditional huitlacoche production remains very labor intensive today. Farmers rely on skilled field laborers to identify and collect the infected corn ears. Huitlacoche harvesting requires recognizing the perfect stage of maturity through sight and feel. The delicate galls must also be removed carefully by hand. This traditional manual harvesting preserves quality.
How is Huitlacoche Prepared and Eaten?
Fresh huitlacoche galls are delicate and must be cooked gently to preserve texture and flavor. The traditional preparation in Mexican cuisine is to rinse the galls and then sauté them lightly. They are often combined with aromatic ingredients like garlic, onions, and epazote before stuffing into quesadillas or tamales. The earthiness of huitlacoche pairs well with corn masa and cheese.
Huitlacoche’s soft texture also lends itself well to soups. It can be simmered into broths or stews with vegetables like squash, zucchini, and mushrooms. Scrambled with eggs or folded into an omelet, the subtle sweetness of huitlacoche shines through. It is often used as a filling for tlacoyos, which are oval shaped fried corn masa cakes in Mexican cuisine.
As huitlacoche has gained international prominence, chefs have come up with innovative culinary preparations. It brings a complex, savory flavor to risotto, tacos, pizza, and even can be incorporated into a sauce for pasta. Huitlacoche blues or stuffed into ravioli highlight its rich, earthy qualities. It also pairs well with robust meats like lamb, beef, and game in entrées.
Preserved huitlacoche also has culinary uses, though it lacks the supple texture of the fresh galls. Canned or frozen huitlacoche is often added to quesadillas, soups, and stews to lend its flavor. Dried huitlacoche is ground into a powder that can flavor sauces, creams, and fillings.

Huitlacoche’s traditional role in central Mexico has expanded internationally, bringing its flavors across borders.ilibrium continues to exist at the habitat level among home ranges.
The Habitat Level and Ecosystem Processes
Ecosystems depend on habitat-level processes, which in turn emerge from the interaction of organisms within their home ranges. Various phenomena must occur to maintain ecosystem function:
– Nutrient cycling – Organisms obtain nutrients from their habitats and return nutrients to the system upon death/decomposition. Without this cycling, nutrients would become depleted over time.
– Energy flow – Energy enters the ecosystem as sunlight, chemosynthesis, or organic matter. It then passes between organisms through consumption and is lost as heat. This movement of energy powers ecosystem processes.
– Population dynamics – Birth, death, immigration, and emigration of individuals determine population sizes. Populations must be regulated to avoid depletion of finite resources.
– Natural disturbance – Events like fires, floods, windstorms, etc. alter ecosystem structure. Disturbance resets the habitat to prevent any one species from dominating permanently.
– Hydrological cycling – Water cycles through the ecosystem via precipitation, surface flow, infiltration, groundwater storage, evapotranspiration, etc. This regulates moisture availability for organisms.
– Succession – Gradual change in community composition over time progresses the habitat toward climax. Early colonizing species are replaced by longer-lived species.
These interactive processes across the habitat allow the larger ecosystem to remain productive and resilient. Sustaining these habitat-level phenomena requires the dynamic equilibrium created by organisms within their home ranges.
