Shredded mushrooms and glass noodles mimic the texture of shark fin in an ethical, savory broth. This protein-enhanced, sustainable family soup delivers the classic banquet experience without environmental harm.
Soak the glass noodles in warm water for 15 minutes, then drain and cut into 2-inch lengths.
Thinly slice shiitake and enoki mushrooms. Shred cooked chicken breast by hand for best texture.
Bring the low-sodium chicken stock to a gentle simmer over medium heat. Add the mushrooms and shredded chicken; simmer uncovered for 10 minutes to release flavors.
Add the soaked glass noodles and green onions. Stir in soy sauce, oyster sauce, salt, and white pepper. Simmer an additional 5 minutes.
In a small bowl, whisk cornstarch with cold water until smooth. Stir this slurry into the soup, then let simmer until slightly thickened (about 2 minutes), stirring constantly to prevent lumps.
Slowly pour in egg whites while stirring the soup in one direction to create silky ribbons. Remove from heat immediately when the egg whites set.
Add sesame oil for aroma, adjust seasoning if needed, and serve hot.
