Maitake mushrooms, with their feathery texture, transform into shreds for tacos. Simmer them down in flavorful beer and citrus, then crisp them up with a little brown sugar.
Allergen Note: Contains milk.
Separate the mushrooms into bite-size pieces. In a sauté pan over medium heat, combine the mushrooms, 1 cup of beer or water, the juice of the orange, 2 tablespoons olive oil, 2 teaspoons of the adobo seasoning, and a pinch of salt. Bring to a simmer, turn down the heat to maintain, cover partially with a lid, and cook, stirring occasionally, until the mushrooms are tender and the liquid has mostly evaporated, about 20 minutes.
Remove the lid, turn up the heat to medium-high, and add 1 tablespoon olive oil, 1 tablespoon soy sauce, and 1 teaspoon firmly packed brown sugar. Sauté until crispy at the edges, 5 minutes longer. Season with salt to taste.
Meanwhile, finely chop about ½ shallot. Pick the cilantro, toss the stems, and chop the leaves. In a small bowl, combine equal parts shallot and cilantro, and drizzle with the juice of ½ lime. Cut the remaining lime into wedges for serving.
In a small saucepan over medium heat, reheat the black beans with a splash of water, about 3 minutes. Season to taste with salt.
To warm the tortillas, in a dry pan over medium-high heat, flash the tortillas for 30 seconds on each side. Wrap them in a clean towel to steam through and keep warm.
To build the tacos, place the tortillas on plates, doubling up, if you like. Fill with the mushrooms and the shallot-cilantro mixture, dollop with the avocado crema, and squeeze with lime. Serve warm, with the beans on the side, and hot sauce, if you want a kick.
