Instructions

  1. Heat a wok or 12-inch heavy skillet over high heat until a bead of water dropped onto cooking surface evaporates immediately. Add oil, swirling it around wok, and heat until it begins to smoke.
  2. Add bacon and stir-fry until brown and crisp, about 3 minutes. Transfer with a slotted spoon to paper towels to drain and reserve for another use.
  3. Add scallions and garlic to bacon fat and stir-fry until fragrant, about 1 minute. Pour broth down side of wok (it will bubble vigorously), add salt and pepper, and bring to a boil. Add mushrooms, then reduce heat and simmer, uncovered, turning occasionally, until tender, about 5 minutes.
  4. Transfer mushrooms to a bowl with a slotted spoon and, when cool enough to handle, cut into 1/4-inch-thick slices. Drizzle liquid over mushrooms if desired.
