Crack the eggs then add 2 tablespoons of water. Beat lightly until the whites and yolks are fully integrated. Set aside.
Pour the broth into a saucepan/pot. Bring it to a full boil then turn the heat down to a gentle simmer.
Season the broth with salt, white pepper, and sesame oil. Taste to adjust.
In a small bowl, mix cornstarch with 6 tablespoons of water until combined (make sure no starch sinks to the bottom). Gradually pour it into the broth while stirring with a spoon.
Turn the heat to the lowest so the broth is at a bare simmer. Pour the beaten eggs in a thin stream while slowly swirling with the spoon.
Transfer the soup to individual bowls. Garnish with scallions and serve immediately.

Notes
1. If the broth is unavailable, you may use water flavored with chicken powder, mushroom powder, MSG, etc.2. You may not need to add salt if the broth you use is already salted.3. Tip on the color: If you’d like to achieve the bright yellow color you often find in restaurant versions, add some turmeric powder while heating the broth.4. Store and reheat: Leftover soup can be stored in the fridge for 2 days. I don’t recommend you freeze egg drop soup as the egg changes texture this way. You may freeze the seasoned, thickened broth. Defrost, reheat and add the egg before serving.
