Hot and Sour Soup Recipe California-Style Delivers Classic Chinese Restaurant Flavour

Hot and sour soup is a Chinese restaurant style soup that many people know from menus in the United States. This recipe aims to match the taste served in several Chinese restaurants in California. It uses chicken stock, soy sauce, vinegar, pepper, chilli sauce, tofu, and egg to make a soup that is both sharp and warming.

This hot and sour soup serves 4 people and takes about 15 to 20 minutes. The method is simple and uses quick simmering and a cornflour slurry to thicken the broth. You add the egg at the end in a thin stream, which gives the soup soft egg threads.

Use chicken stock for the main flavour, then balance it with vinegar and black pepper. Mushrooms, bamboo shoots, and tofu add texture more than taste in this version. Measurements below include both common kitchen measures and metric amounts to help with home cooking.

• Chicken stock or broth: 6 cups (about 1.4 litres)
• OR water: 4 cups (about 950 ml) + chicken bouillon cubes: 4 cubes
• Soy sauce: 4½ tbsp (about 67 ml)
• Cooked shredded chicken or pork: ⅓ cup (about 50 g)
• Mushrooms, diced: ¾ cup (about 55–75 g)
• Garlic chilli sauce (chilli paste): ¾ tbsp (about 11 ml)
• Freshly ground black pepper: ⅓ tsp (about 1 g)
• White vinegar: ⅓ cup (about 80 ml)
• Canned bamboo shoots, julienned: ½ cup (about 75 g, drained)
• Firm tofu: 4½ oz (about 125 g), cut into ¼-inch (about 6 mm) dice
• Cornflour (cornstarch): 3 tbsp (about 24 g)
• Cold water (for slurry): 2 tbsp (about 30 ml)
• Egg: 1, beaten
• Green onions (spring onions): 3 stalks, diced (including tops)
• Toasted sesame oil: ¾ tsp (about 4 ml)

Equipment

This soup cooks in one pot, so clean-up is quick. Use a small saucepan so the soup stays at a steady simmer. A cup helps you mix the cornflour slurry and beat the egg before you add them. A spoon or ladle helps you stir without breaking the tofu.

• 2-quart saucepan (about 2 litres)
• Measuring cups and spoons
• Knife and chopping board
• Small cup or bowl (for slurry)
• Small cup or bowl (for beaten egg)
• Spoon or ladle

Step-by-step procedure

Keep the broth at a simmer, not a hard boil. This helps the soup stay clear and keeps the tofu cubes in shape. Add the thickener slowly and stir well, or it can clump. For the egg, pour in a thin stream and wait briefly so the strands form.

1. Bring the chicken stock to a simmer in a 2-quart (2-litre) saucepan.
2. Add soy sauce, shredded meat, mushrooms, and garlic chilli sauce. Simmer for 5 minutes.
3. Add black pepper, white vinegar, bamboo shoots, and tofu. Simmer for 5 minutes.
4. Mix cornflour with cold water in a cup. Stir until smooth.
5. Pour the cornflour mixture into the soup while stirring well.
6. Simmer for 5 minutes, until the soup thickens.
7. Beat the egg until mixed. Pour it slowly into the soup in a fine stream.
8. Stir the soup several times, then wait 30 seconds.
9. Add green onions and sesame oil. Stir well and remove from the heat.
10. Serve hot.

Flavour balance: hot and sour

The "sour" part mainly comes from white vinegar, and the "hot" part comes from black pepper and garlic chilli sauce. Soy sauce adds salt and colour. If the soup tastes too sharp, reduce vinegar first. If it tastes flat, add a little more soy sauce, then adjust heat.

Texture notes

In this recipe, mushrooms, bamboo shoots, and tofu mainly change mouthfeel. They do not add a strong taste, but they make the soup feel hearty. Dice the tofu into small even cubes so it warms fast. Keep bamboo shoots thin so they stay easy to chew.

Tips and variations from the recipe

You can adjust vinegar, black pepper, garlic chilli sauce, and soy sauce to taste. The recipe notes that American vinegar can be more acidic than Chinese vinegar. Start with less vinegar and add slowly. You can also add or remove mushrooms, bamboo shoots, or tofu as needed.

Serving

Serve this Chinese hot and sour soup right after you add sesame oil and spring onion. The aroma is strongest at this point. It suits a light meal or a starter before noodles or rice. If the soup sits, it can thicken more, so reheat gently and stir well.
