Chinese Hot and Sour Soup (Suan La Tang)
Suan la tang: the ubiquitous hot-and-sour soup of Chinese restaurant menus. The Sichuan version (the original): tofu, wood ear mushroom, lily buds, shredded pork, egg ribbons in a broth seasoned with white pepper, Chinkiang vinegar, and soy — the sourness from vinegar, the heat from white pepper (not chili). The Beijing-restaurant version has evolved to use chili — this is the more common international version.

The Method
1
Soak the dried wood ear mushrooms and lily buds separately in cold water until fully rehydrated and pliable. Trim the woody stems from the wood ear and shred; remove the hard tips from the lily buds and tear each in two. Cut the tofu into fine strips and shred the pork to a similar dimension. All components should be uniform so they cook at the same rate — the prep is done when every element is cut and ready.
2
Bring the stock to a full boil in a medium pot. Add the shredded pork, separating the strands as they go in. Add the wood ear mushroom and lily buds. Return to a boil and simmer briefly until the pork has lost all pink colour — the signal that the aromatics have begun to exchange with the broth.
3
Add the tofu strips and the soy sauce. Stir the cornstarch-and-cold-water slurry once more to recombine it, then pour it into the simmering broth in a slow, steady stream while stirring continuously. The soup is ready to receive the egg when it has thickened to a consistency that coats the back of a spoon lightly — not gluey, not thin.
4
This is where the dish lives or dies. Hold the beaten eggs above the pot and pour them in the thinnest possible stream while stirring the soup in one continuous circular motion. The current of the broth sets the egg instantly into long, silky ribbons. If the stream is too thick or the stirring stops, the egg scrambles into clumps and the characteristic texture is lost — the ribbons must be distinct, fine, and suspended throughout.
5
Remove the pot from the heat. Add the Chinkiang vinegar and ground white pepper only now — prolonged heat dulls the vinegar's complexity and flattens the pepper's penetrating quality. Stir once. Taste: the soup should carry a sharp, immediate sourness and a deep, warming heat that builds at the back of the palate rather than on the tongue.
From the canon — Chinkiang vinegar (镇江醋, Zhenjiang hei cu, Zhenjiang black vinegar) is China's most celebrated vinegar — a dark, complex, aged rice vinegar produced in Zhenji… Chinkiang Vinegar (镇江醋 Zhenjiang Hei Cu) — The Black Vinegar of Jiangsu →

Ladle into bowls and drizzle each portion with toasted sesame oil. Serve immediately, with extra Chinkiang vinegar and ground white pepper on the table for each diner to adjust.

Quality Hierarchy
01
Reserve — Hand-pulled pork from heritage-breed pig; Chinkiang vinegar of three years' aging; home-rendered stock from a long-simmered pork or chicken carcass; freshly dried wood ear and lily buds from a Chinese specialist.
02
Estate — Good-quality fresh pork fillet; labelled Chinkiang vinegar (镇江香醋) from a reputable producer; shop-bought but unsalted pork or chicken stock; dried wood ear and lily buds from an Asian grocery.
03
Market — Supermarket pork; standard Chinkiang vinegar; liquid stock from a carton, low-sodium preferred; packaged dried mushrooms; fresh block tofu.
04
House — Any lean pork; rice vinegar in place of Chinkiang (simpler, less complex); stock cube broth; silken tofu (texture will differ); pre-sliced wood ear if dried is unavailable.

Sensory Tests
◇Sight. The pork strands have turned fully white with no pink remaining before the tofu is added.
◇Sight. After the cornstarch slurry is incorporated, the broth coats the back of a spoon with a light, even film — neither watery nor paste-like.
◇Sight. The egg has set into long, distinct, fine ribbons suspended through the soup — not clumped, not dissolved.
◇Touch. The wood ear mushroom, when pressed between fingers after soaking, yields with a slight resistance and a clean snap — properly rehydrated, not still leathery.
◇Where it lives or dies. The egg must be poured in the finest possible stream into a stirring broth — this alone determines whether the soup has silky ribbons or broken scrambled curds.

What to Pour
A light, off-dry Chinese rice wine (Shaoxing served warm) or, at table, a cold Tsingtao-style lager — its mild carbonation and clean finish cut the vinegar's acidity without competing with white pepper's heat. A pale, high-acid white such as Picpoul de Pinet is also serviceable.
