Fermented tofu develops a distinctive white mold coating and is pan-fried until crispy in this Anhui specialty. A regional curiosity rich in protein, this vegetarian delicacy offers a unique umami flavor unlike any other tofu dish.
Cut hairy fermented tofu blocks into thick slices, about 1-inch thick, to ensure the texture remains soft inside and crisp outside.
Pat tofu slices gently with a paper towel to wick away excess moisture, being careful to preserve the delicate mold coating.
Heat neutral oil in a nonstick or seasoned cast-iron skillet over medium heat until shimmering, but not smoking.
Pan-fry tofu slices without crowding, turning every 2–3 minutes, until all sides develop an even, golden-crisp crust, about 10–12 minutes total.
Mix soy sauce, rice vinegar, chili oil, and sugar in a bowl to create a dipping sauce; whisk until sugar dissolves.
Place pan-fried tofu on a serving platter, top with sliced scallions and fresh cilantro, and serve immediately with dipping sauce.
