A hot and sour soup recipe should hit you with two things at once: a clean vinegar sharpness and a slow building heat from white pepper. This version keeps the broth clear, the tofu silky, and the mushrooms chewy without any cornstarch-heavy gloop. You get a bowl that tastes like a proper Sichuan-style starter but uses ingredients you can find in most supermarkets.
The method below builds the sour note from black vinegar and the heat from freshly ground white pepper, then sets the texture with a light cornstarch slurry. It’s a stovetop soup that comes together in about thirty minutes, which makes it realistic for a weeknight. If you like balanced Asian broths, this hot and sour soup recipe will become a reliable fallback.
Why You’ll Love These Hot And Sour Soup
- Clear broth with real tang from black vinegar, not just citrus
- Silky tofu and chewy wood ear mushrooms in every spoonful
- Ready in 30 minutes on a single burner with one pot
- Adjustable heat using white pepper instead of chili oil
- Naturally meat-free and works with pantry staples
Ingredients You’ll Need
- 6 cups vegetable stock, low sodium
- 200 g firm tofu, cut into 1 cm cubes
- 15 g dried wood ear mushrooms, rehydrated and sliced
- 100 g fresh shiitake mushrooms, thinly sliced
- 3 tbsp black vinegar (Chinkiang preferred)
- 1 tsp white pepper, finely ground
- 2 tbsp light soy sauce
- 2 tbsp cornstarch mixed with 3 tbsp cold water
- 1 large egg, lightly beaten
- 1 tbsp sesame oil
- 2 scallions, sliced thin
- 1 tsp salt, adjusted to taste
Ingredient Substitutions
Wood ear mushrooms: Replace with 80 g sliced canned bamboo shoots for a crunchy, mild alternative. Bamboo shoots don’t have the same slippery chew, so the soup feels lighter and less earthy. Add them directly with the shiitake since they need no rehydration, and expect a cleaner, less funky aroma. Making this hot and sour soup at home is surprisingly straightforward once you know the key steps.
Black vinegar: Use 3 tbsp rice vinegar plus 1 tsp molasses if Chinkiang isn’t available. Rice vinegar is sharper and less smoky, while molasses restores some depth and color. The sourness will be brighter and a little one-note, so taste and add an extra half teaspoon of soy sauce for body. The hot and sour soup works well for weeknight cooking when time is limited.
Firm tofu: Swap for 180 g extra-firm tofu pressed for 10 minutes to reduce breakage. Extra-firm holds shape better when stirred into boiling broth but loses some silkiness. Cube it small so the texture stays pleasant rather than rubbery. Storing leftover hot and sour soup correctly keeps it tasting good for days.
White pepper: Use 1 tsp freshly cracked black pepper for a stronger, more nose-clearing heat. Black pepper adds visible specks and a different aromatic, so the soup looks less traditional. Keep the amount equal and add at the end to preserve punch.
Step-by-Step Instructions
- Bring 6 cups vegetable stock to a gentle simmer over medium-low heat in a 4-quart pot, about 5 minutes, until small bubbles form at the edge.
- Add rehydrated wood ear mushrooms and sliced shiitake to the pot. Cook 5 minutes until the shiitake soften and the broth smells earthy.
- Stir in 2 tbsp light soy sauce, 1 tsp white pepper, and 1 tsp salt. Taste the broth now; it should be savory with a peppery backnote, not yet sour.
- Add 200 g tofu cubes and pour the cornstarch slurry while stirring slowly. Keep at medium-low heat for 2 minutes until the broth turns lightly glossy and coats a spoon.
- Remove pot from heat and stream in the beaten egg while stirring in one direction to form thin ribbons. The egg should set into wisps within 20 seconds.
- Stir in 3 tbsp black vinegar and 1 tbsp sesame oil. The vinegar aroma should rise immediately; serve immediately to keep the tang bright.
- Scatter sliced scallions over each bowl. The soup is best enjoyed warm before the pepper dulls.
Pro Tips
Add the black vinegar off the heat so its acidity stays sharp instead of cooking into a flat sourness. For a fuller technique on balancing acid in broths, see acid balance from Bon Appetit.
Rehydrate wood ear mushrooms in warm water for 20 minutes so they lose their brittle edges and turn pliable before slicing. Pair the bowl with stewed potatoes for a heavier meal.
Grind white pepper fresh if you can; pre-ground loses bite within a month and leaves the soup mild. A side course of dumplings works well alongside.
Beat the egg with a pinch of salt so the ribbons stay tender and don’t clump in the hot broth. Use recipe search to find matching appetizers.
Common Mistakes to Avoid
Boiling the broth after adding cornstarch makes the slurry break and turn stringy instead of silky. Keep the heat at medium-low heat once the slurry goes in.
Adding vinegar too early cooks off the sour top note and leaves a dull taste. Always stir it in after you take the pot off the burner.
Skipping the slow stir when pouring egg creates one big lump rather than ribbons. Move the spoon in a steady circle while the egg threads in.
Using silken tofu without pressing leads to crumbles that disappear into the broth. Firm tofu holds the cube shape better in this broth style.
Serving Suggestions
Place the soup in small bowls before a noodle dinner so it reads as a starter rather than a main. A sprinkle of extra scallion keeps the plate fresh.
Offer pork chops after the soup if you want a full meat course, since the light broth preps the palate. Steamed rice on the side absorbs the last drops.
For lunch, serve a larger portion with crusty bread to dip, though that breaks from tradition. The pepper heat wakes up a sleepy midday meal.
Storage and Reheating
Cool the soup within 2 hours and store in an airtight container for up to 3 days in the fridge. The tofu will firm slightly but stay edible.
Reheat on medium-low heat to a steaming temperature near 74°C, stirring once, then add a fresh splash of vinegar to revive the sour note. Freezing isn’t ideal since tofu turns spongy, so skip the freezer for this batch.
Don’t leave the pot out after dinner; bacteria grow fast in starch-thickened broth. Label the container with the date using recipe keys if you meal plan.
Recipe Variations
Chicken Version
Add 150 g shredded cooked chicken with the tofu in step four for extra protein. The meat warms through in 2 minutes and gives the broth a fuller body without changing the sour profile.
Extra Spicy Bowl
Double the white pepper to 2 tsp and add 1 tsp chili flakes with the soy sauce. The heat becomes throat-warming rather than background, so cut the vinegar by half a tablespoon to keep balance.
Low-Starch Option
Skip the cornstarch slurry and use 1 extra tbsp black vinegar for mouthfeel. The broth stays thin but tangy, and the tofu carries the texture instead of the gel.
Mushroom Heavy Mix
Replace tofu with 120 g more shiitake and 50 g oyster mushrooms for a vegan, protein-light bowl. Cook the extra mushrooms 5 minutes longer so they release their juice into the stock.

Ingredients
Instructions
-
Simmer the stock
Bring 6 cups vegetable stock to a gentle simmer over medium-low heat in a 4-quart pot, about 5 minutes, until small bubbles form at the edge of the pot. Do not let it reach a rolling boil at this stage so the broth stays clear.
-
Cook the mushrooms
Add rehydrated wood ear mushrooms and sliced shiitake to the pot. Cook for 5 minutes over medium-low heat until the shiitake soften and the broth smells earthy.
-
Season the broth
Stir in 2 tbsp light soy sauce, 1 tsp white pepper, and 1 tsp salt. Taste the broth now; it should be savory with a peppery backnote, not yet sour, so adjust salt if needed.
-
Add tofu and slurry
Add 200 g tofu cubes and pour the cornstarch slurry while stirring slowly. Keep at medium-low heat for 2 minutes until the broth turns lightly glossy and coats a spoon without becoming stringy.
-
Stream the egg
Remove pot from heat and stream in the beaten egg while stirring in one direction to form thin ribbons. The egg should set into wisps within 20 seconds and look like soft threads floating in the broth.
-
Add vinegar and oil
Stir in 3 tbsp black vinegar and 1 tbsp sesame oil off the heat. The vinegar aroma should rise immediately; serve at once to keep the tang bright and sharp.
-
Scatter scallions
Scatter sliced scallions over each bowl just before serving. The soup is best enjoyed warm before the white pepper heat dulls with time.
