Mushroom “Carnitas” Tacos with Chipotle-Lime Mayo

In our riff on the much-loved carnitas tacos, meaty king oyster mushrooms stand in for the traditional slow-braised pork shoulder. Prepared in a slow cooker with chipotle chiles, cumin, garlic, and fresh citrus juice, they emerge meltingly tender, then are quickly browned to give them the crispy edges that are the hallmark of well-made carnitas. Tuck these mushrooms inside warm tortillas, top with your favorite fixings, and dig in.
