Directions
Step 1: Prepare the Pickling Liquid
Combine the apple cider vinegar, water, sugar, kosher salt, Mexican oregano, and smashed garlic clove in a small saucepan. Place the saucepan over medium heat and bring the mixture just to a simmer. Stir gently until the sugar and salt have dissolved.
Step 2: Pickle the Red Onions
Place the thinly sliced red onion in a heat-safe jar or bowl. Carefully pour the warm pickling liquid over the onions, making sure the slices are evenly coated.
Allow the onions to cool to room temperature, then cover and refrigerate them for at least 30 minutes. The flavor will become even more developed if the onions are allowed to pickle for several hours.
Step 3: Soften the Guajillo Chiles
Place a dry skillet over medium heat. Add the guajillo chiles and toast them for approximately 20 seconds per side, just until they become fragrant. Watch them carefully to prevent burning, which can make the sauce taste bitter.
Transfer the toasted chiles to a heat-safe bowl and cover them with hot water. Let them soak for 10 minutes, or until softened.
Step 4: Char the Vegetables
While the chiles soak, place the Roma tomatoes, white onion, and garlic cloves in a skillet or beneath the broiler. Cook, turning occasionally, until the vegetables are softened and lightly charred on all sides.
The charred surfaces give the taquera sauce its characteristic roasted flavor and complement the earthiness of the huitlacoche.
Step 5: Blend the Taquera Sauce
Drain the softened guajillo chiles and place them in a blender. Add the roasted tomatoes, onion, garlic, chipotle pepper, apple cider vinegar, cumin, and kosher salt.
Blend until the mixture is completely smooth. Use care when blending warm ingredients and allow steam to escape according to the blender manufacturer’s directions.
Step 6: Cook the Taquera Sauce
Heat 1 tablespoon olive oil in a saucepan over medium heat. Carefully pour the blended sauce into the pan.
Simmer for 10 to 12 minutes, stirring occasionally, until the sauce has darkened slightly and reached a lightly thickened consistency.
Taste the finished sauce and adjust the seasoning if needed. Keep it warm over low heat while preparing the taco filling.
Step 7: Sauté the Aromatics
Heat the unsalted butter and 1 tablespoon olive oil in a large skillet over medium heat. Add the diced white onion and cook for approximately 5 minutes, stirring occasionally, until softened.
Add the minced garlic and cook for 1 additional minute, stirring frequently so the garlic does not burn.
Step 8: Cook the Huitlacoche Filling
Add the fresh or thawed huitlacoche to the skillet. Stir in the epazote, kosher salt, and black pepper.
Cook the mixture for 8 to 10 minutes, stirring occasionally, until the huitlacoche is tender and the excess moisture has evaporated. The finished filling should be moist and rich but not watery.
Step 9: Add the Truffle Essence and Lime
Remove the skillet from the heat. Gently stir in the black truffle essence or truffle oil and the fresh lime juice.
Add the truffle ingredient only after removing the pan from the heat so its delicate aroma remains noticeable. Stir carefully and avoid adding more than the listed amount, as the truffle flavor should support the huitlacoche rather than dominate it.
Step 10: Warm the Corn Tortillas
Heat a clean, dry skillet over medium heat. Warm each gluten-free corn tortilla for approximately 30 seconds per side, or until soft, flexible, and heated through.
Transfer the tortillas to a clean kitchen towel and keep them covered while warming the remaining tortillas. This helps retain their moisture and prevents them from becoming brittle.
Step 11: Assemble the Huitlacoche Tacos
Divide the warm huitlacoche filling evenly among the eight corn tortillas. Top each taco with a drizzle of taquera sauce, crumbled queso fresco, pickled red onions, avocado slices, and fresh cilantro.
Finish each taco with a squeeze of fresh lime juice. Add an optional cheese crisp for extra texture and an elegant finishing touch.
Step 12: Serve
Serve the tacos immediately while the tortillas and huitlacoche filling are warm. Offer additional taquera sauce, pickled red onions, and lime wedges at the table so each person can customize the tacos to taste.
Notes
Huitlacoche is a delicacy created when corn is naturally affected by the fungus Ustilago maydis. It is sometimes called Mexican corn truffle because of its dark color and rich, earthy, mushroom-like flavor.
Fresh huitlacoche may be available seasonally. Frozen huitlacoche is an excellent alternative and can often be found at Latin markets or specialty food stores. Thaw frozen huitlacoche before measuring and cooking it.
Black truffle essence and truffle oil can vary considerably in strength. Use the measured amount sparingly the first time you prepare the recipe. The aroma should complement the huitlacoche without masking its natural flavor.
Epazote is a traditional Mexican herb with a distinctive earthy flavor. Fresh epazote may be available at Latin markets, but dried epazote can be used when fresh is unavailable.
Cotija cheese may be substituted for the queso fresco if you prefer a firmer texture and saltier flavor.
For the safest gluten-free preparation, verify that the corn tortillas, chipotle pepper in adobo sauce, dried chiles, seasonings, cheese crisps, truffle product, and other packaged ingredients are labeled appropriately for your needs. Prevent cross-contact by using clean cookware, utensils, preparation surfaces, and serving dishes.
Store leftover huitlacoche filling in an airtight container in the refrigerator for up to 3 days. Reheat it gently in a skillet before serving.
Store the taquera sauce and pickled red onions in separate covered containers in the refrigerator. Keep the tortillas, cheese, avocado, and cilantro separate so the tacos can be assembled just before serving.
