In a medium pot, heat the vegetable oil over medium-high heat. Add the garlic and ginger, and cook for 30 seconds until fragrant.
Add the sliced mushrooms and cook for 2–3 minutes until softened.
Pour in the chicken stock and bring to a simmer. Stir in the soy sauce, rice vinegar, chili garlic sauce, sugar, and white pepper. Taste and adjust seasoning.
Finishers
Gently stir in the cubed tofu and simmer for 2 minutes to warm through.
Whisk together the cornstarch and cold water. Stir the slurry into the soup and cook until the broth thickens, about 1 minute.
Slowly drizzle in the beaten eggs, stirring gently to create silky ribbons.
Remove from heat. Stir in green onions and drizzle with sesame oil. Serve immediately.
Notes
Over several trials, I found that sautéing the garlic and ginger just 30 seconds prevents any bitterness.When adding the cornstarch slurry, make sure to whisk it into cold water first to avoid lumps and achieve a glossy finish.This soup stores beautifully for up to 4 days in the fridge; reheat gently and add a splash of stock to refresh the texture.
