Huitlacoche (Mexican Truffle) Spores (Ustilago maydis)

Huitlacoche (Ustilago maydis), also known as Mexican truffle, is a fungus that grows on various parts of the corn plant, most commonly on the ears. It is a true delicacy in Mexican cuisine and has been known to sell for very high prices, sometimes up to $88 per kg.

We love to cook it the same day we find it — gently sautéed in butter with vegetables, added to a risotto, or tucked into a huitlacoche quesadilla. Simply delicious!

Here, you receive a small packet of spores. To inoculate your corn, mix the spores thoroughly into water, then apply the solution to young corn ears by pouring it over the silks, using a syringe or spray bottle. Warm, slightly humid conditions help encourage development.

There is no guarantee it will work, however. Huitlacoche formation depends on many factors, including weather, corn growth stage, and soil conditions. Harvest when the galls are still young, tender, and silvery grey, before they become too dark and mature.

A teaspoon of spores. Likely 1000s of spores.
