- My egg clumped together.
- You poured too fast or didn't stir the soup enough. The water must be moving (creating a vortex) when you drizzle the egg.
- Not sour enough.
- Vinegar flavor fades during cooking. Add a splash more at the very end, right before serving.
Hot and Sour Soup Base
The secret to Hot and Sour soup (or thick sauce) is 'velveting'. The contrast of vinegar (sour) and white pepper/chili (hot) is softened by egg and starch. The 'egg drop' technique in the soup is not just visual but adds texture: in the hot, thickened liquid, the egg sets in thin, silky ribbons rather than a solid lump.

Instructions
1
✓
Grate the ginger and garlic. Beat the egg in a small bowl with a fork, as if making scrambled eggs.
Tip: The egg should be completely uniform.
2
✓
In a saucepan, bring the stock, soy sauce, sugar, grated ginger, garlic, and chili to a boil.
Tip: Let it simmer for a few minutes to infuse the flavors.
3
✓
Pour in the vinegar.
Tip: Vinegar is added later so it keeps its sharp 'bite'.
4
✓
Mix the cornstarch with cold water, then pour into the soup. Stir until thickened.
Tip: It is important to thicken first, then add the egg! The egg disperses beautifully in the thickened liquid.
5
✓
Here is the trick: Stir the soup in a circular motion (create a vortex) and slowly drizzle the beaten egg in a thin stream. Don't stir wildly, just let the hot soup 'cook' the egg ribbons.
Tip: This creates those beautiful floating 'clouds'.
6
✓
Turn off the heat immediately.
Tip: The egg takes only seconds to cook.
