Anhui Hairy Tofu

Anhui·Medium·9 min

The fluffy texture of the tofu, covered in a thin layer of mold, transforms into a rich, savory delight when fried.

Developed in Huizhou (now Anhui's Huangshan/Yi County area) at least by the Ming dynasty (14th–17th century), where merchants spent weeks on the road and fresh tofu spoiled fast. Letting Mucor mold colonize the surface preserved the protein and intensified flavor — the same logic as European mold-ripened cheese, applied to soy. Still made at home in Yi County by leaving tofu on rice straw for 3–5 days.

Huizhou (Yi County) staple, in use by the Ming (14th–17th c.) when traveling merchants needed protein that wouldn't spoil. The fuzz is Mucor or Actinomucor mycelium — same family as 腐乳 — secreting proteases that pre-digest soy into amino acids. Must be alive when it hits the oil.

Tofu blocks coated in a soft white fuzz like cotton wool, pan-fried until the fuzz crisps brown and the inside turns custardy. Served with chili-soy dip and chopped scallion. Texture is the point: crackly skin, near-liquid center, mushroom funk on the tongue. Street vendors fry it on a flat pan; the fuzz must be alive when it hits the oil.

The fuzz is Mucor or Actinomucor mold mycelium — same family used in Chinese fermented bean curd (furu). It secretes proteases that pre-digest the soy protein into amino acids and free glutamates, which is why fried hairy tofu tastes far more intense than fresh. Frying must be hot and brief: too long and the mycelium turns bitter; too short and the funk doesn't render.

Variations

Yi County street vendors fry on flat irons with chili-soy dip; Tunxi Old Street sells it skewered with sweet rice wine; Wuhu version pairs it with a hot bean sauce; modern Shanghai Anhui restaurants temper the fuzz to 2–3 days for a cleaner, milder funk.

Cook to learn

Fry the mold-ripened tofu hot and brief: the fuzzy Mucor mycelium is what makes this tofu taste deep and cheesy, but a quick sear over real heat renders that funk and crisps the skin — drag it out and the mycelium turns bitter, rush it cold and the flavor never wakes up.

How it's made

4 steps · 9 min

1
2 min
Heat a generous amount of chili oil in a wok over medium heat until it shimmers. Add the garlic, finely minced, and stir-fry until it releases its fragrant aroma, about 1 minute.
Watch out
Heat the chili oil until it just shimmers and thins, then add garlic — too cold and it won't bloom, too hot and the garlic burns black and acrid before the tofu even goes in.
2
3 min
Gently add the fermented tofu and tofu cubes to the wok. Stir carefully to coat them in the oil and garlic, and cook until the tofu begins to brown slightly on the edges, about 3 minutes.
Watch out
Let the tofu sit undisturbed until the edges turn golden and a crust sets — that's the funk rendering and the skin crisping; only then nudge it.
3
2 min
Add the fermented black beans and sliced chili pepper. Stir-fry for another 2 minutes until the beans are fragrant and the chilies soften.
4
2 min
Pour in the soy sauce and continue to stir-fry, allowing the flavors to meld and the tofu to absorb the sauce, about 2 minutes. Finish with freshly chopped scallions.
Watch out
Pour the soy down the hot side of the wok so it sizzles and caramelizes, then toss just until the tofu drinks it in — a few seconds, not a long braise.
