Huitlacoche, a Mexican Fungus, is Popping Up On Restaurant Menus Across the US

Carolina Aboumrad, a restaurant supplier, was having lunch at a Mexican eatery in Los Angeles. While chatting with the server, she mentioned she sources truffles, rare mushrooms and other specialty ingredients for chefs. The next thing she knew, the restaurant’s own chef was coming out of the kitchen. “He told me, ‘my dream ingredient is huitlacoche. I cannot get it anywhere except for in a can,’” Aboumrad recalls.

A prized pre-Hispanic ingredient in Mexico, huitlacoche is a bluish-gray fungus that grows on corn kernels and causes them to swell into bulbous masses, usually after rainy seasons. The ingredient’s seasonality, as well as the way it originates from corn, has made huitlacoche a treasured food and a symbol of bounty in Mexican culture. “Corn was the food of the gods and allowed the Aztecs to flourish,” explains Aboumrad. “When huitlacoche came out, it was like a gift from the gods.”

With its deeply earthy, smoky flavor, the tender, spongy ingredient is considered a culinary delicacy in Mexico. Vendors on the streets of Mexico City fold huitlacoche into blue corn tortillas to make quesadillas, while home cooks might add the ingredient to sauces and soups, fold it into tacos or wrap it inside tamales. Hugo Ortega, the chef behind the Houston restaurant Xochi, especially enjoys the rich flavor of huitlacoche when sautéed with eggs, a recipe he learned as a boy while living with his grandmother in Acatlán de Osorio, a city in the east-central Mexican state of Puebla. “The silkiness and earthiness,” he says, “it’s delicious.” Thanks to its high protein and fatty acid contents, huitlacoche is also regarded as a nutrient-rich food with medicinal properties. The spores, though, are highly dependent on optimal weather and soil conditions. “Its scarcity creates a naturally higher price point,” says Jorge Gaviria, cookbook author and founder of masa company Masienda. 

In the US, fresh huitlacoche is even harder to find. When corn farmers spot the fungus growing in their fields, many farmers—unacquainted with its cultural significance south of the border—consider it a scourge, and they destroy the affected crops. Deliberate cultivation of huitlacoche isn’t easy either, says Aboumrad, as much of the corn grown domestically is genetically modified to be fungus-resistant. “It’s not like you can just inoculate a field and it’s going to take,” she explains. 

Although rare, huitlacoche does appear in some farmers markets in the US (Ortega finds it at Azteca Farmers Market in Houston), especially as more growers become aware of its culinary value and cultural importance. Jeremy Umansky, the chef and owner of Cleveland’s Larder Delicatessen and Bakery, now obtains a steady supply of huitlacoche ever since he approached the Amish corn farmers at the North Union Farmers Market and shared with them his interest in the fungus, the price he was willing to pay (up to $1.50 per ear wholesale) and best storage practices to prevent spoilage. “Imagine if farmers in America weren’t conditioned to think that huitlacoche was bad,” says Umansky. “The sheer volume of fungicides that we would stop using, and the amount of money that farmers could bank, is massive.”

Even importing huitlacoche from Mexico to the US has its hurdles. “Once you have it, you only have a few days to use it,” explains Ricardo Olvera, Aboumrad’s business partner. Huitlacoche is largely cultivated in Puebla and Oaxaca, located in Mexico’s central and southern regions, respectively. That makes for a long journey to the US with a highly perishable fungus. 

But it can be done. After finally finding a steady and reliable supplier in Oaxaca and in Puebla, Aboumrad and Olvera launched a company devoted to importing the ingredient—Huitla. To prevent spoilage, the team immediately refrigerates every shipment upon its arrival in the US, then quickly ships the orders directly to customers. 

While Aboumrad enjoys traditional huitlacoche preparations of her native Mexico, “I’m more interested in seeing what a modern application of huitlacoche looks like,” she says, recalling a recent dinner she ate at Taco María in Costa Mesa, California, where chef Carlos Salgado served a nutty, savory huitlacoche butter alongside blue cornbread. 

Plenty of other new and unexpected applications are showing up in restaurant kitchens from coast to coast. Osito in San Francisco has featured cuttlefish with lacto-fermented huitlacoche sauce on its tasting menu. Umansky’s Larder has topped poutine with a huitlacoche-based gravy. Ortega’s Xochi offers a dish he calls huitlasquites, a corn soup starring the velvety Mexican delicacy. Chef Lawrence Smith’s Mexican-inspired restaurant Chilte in Phoenix, Arizona incorporates the fungus into a pasta dish with mezcal-scented beurre blanc, goat cheese and smoked ant salt.

Researchers are investigating how to optimize huitlacoche’s cultivation in Mexico and the US. Commercial and culinary interest in the fungus is mounting both in and outside its country of origin, as driving forces such as travel, social media and migration “allow us to experience and access cultures in ways that we’ve never had before,” says Gaviria. However people use huitlacoche, he believes that, as more people respectfully adopt ingredients from different cultures into their lives, even in non-traditional applications, the more cultural recognition and awareness will develop around different cuisines. Smith agrees, pointing out that, “as we open our minds and palates, we can destigmatize ‘exotic’ foods.”

While the growing availability of huitlacoche is certainly related to chefs’ interest in the ingredient, there’s also “a mushroom craze going on right now,” says Olvera. Aboumrad recalls that lion’s mane was not popular several years ago, and many of the chefs she approached weren’t interested. “Now, you see it at every Whole Foods. You see supplements with mushrooms in it,” she says. This excitement could make way for more varieties of fungi like huitlacoche to find their way onto restaurant menus and into home kitchens across the US.

The Mexican delicacy is far from being a plague, adds Olvera. “It’s just this beautiful transformation of corn.”
