About this recipe

Huitlacoche quesadillas are a pre-Hispanic delicacy that combines the corn tortilla with huitlacoche (corn smut), a fungus that grows on maize cobs and is considered the Mexican truffle. The huitlacoche is sauteed with onion, garlic, chilli and epazote, then stuffed into tortillas with cheese to create quesadillas with an earthy, umami and deeply Mexican flavour.

History & Origin

Huitlacoche (Ustilago maydis) is a parasitic fungus that infects maize cobs, transforming the kernels into grey-blue tumours full of spores. Whilst in other countries it is considered a blight, in Mexico it is a gourmet ingredient revered since pre-Hispanic times. The Aztecs called it cuitlacochin and considered it a delicacy worthy of nobility. Its flavour is complex: earthy, smoky, slightly sweet, with intensified corn notes and a deep umami that contemporary chefs compare to European black truffle. Hence it is known as the Mexican truffle or Aztec caviar. Huitlacoche quesadillas are the most popular way to eat it, especially in central Mexico, where during the rainy season (June to October) the markets fill with cobs infected with this prized fungus. The traditional preparation is straightforward: huitlacoche is sauteed with onion, garlic, serrano chilli and epazote (a Mexican aromatic herb), then stuffed into fresh corn tortillas with Oaxaca cheese. In Mexico City markets, the quesadilla makers prepare these delights to order on clay griddles, offering a unique gastronomic experience. Huitlacoche is gaining international recognition in haute cuisine, appearing on menus of Michelin-starred restaurants around the world.

Frequently asked questions

What people ask about this recipe

What is huitlacoche?

Huitlacoche (also spelled cuitlacoche) is an edible fungus that grows naturally on corn ears infected by Ustilago maydis. While considered a crop disease in other parts of the world, in Mexico it has been a culinary delicacy since pre-Hispanic times, often called 'Aztec caviar' or 'Mexican truffle'.

What does huitlacoche taste like?

It has a deep, earthy, umami flavour with notes reminiscent of mushrooms, black truffle and sweet corn. The texture is juicy and slightly gelatinous when cooked. It pairs beautifully with epazote, garlic, onion and fresh cheese, which is why quesadillas are the most popular way to eat it.

Is huitlacoche safe to eat?

Yes, completely safe. Although it is botanically a parasitic fungus on corn, it is not toxic and does not cause common allergies. In fact, it contains proteins, essential amino acids (lysine), beta-glucans and antioxidants that corn alone does not provide. The FAO recognises it as a functional food. It has centuries of documented safe consumption in Mesoamerica.

Where can I buy huitlacoche in the UK?

Fresh huitlacoche is virtually unavailable in the UK, but you can find it tinned or frozen at Mexican specialist shops like MexGrocer, Cool Chile Co. or Sous Chef online. The tinned version is already cooked, ready to use in quesadillas. As a substitute, sauté Portobello mushrooms with a touch of squid ink and sweet corn for a similar earthy, dark profile.

How do you cook huitlacoche?

The traditional method is to sauté it with onion, garlic, serrano chilli and epazote for 8-10 minutes, until it releases its dark juices and concentrates in flavour. It is then used as filling for quesadillas, tamales, sopes, crepes or soups. Tinned huitlacoche just needs warming through; fresh kernels can be cooked whole or chopped.

Why is huitlacoche called 'Aztec caviar'?

Because of its glossy black colour, its high price when sold fresh, and because it was a delicacy reserved for Aztec nobility before the Spanish arrival. Today, chefs worldwide use it in fine dining. In Europe, where corn smut is systematically eliminated, its rarity has elevated it to gourmet status.
