|   |  | 
| 8 |   | cups Homemade Chicken Stock , or canned low-sodium chicken broth, skimmed of fat  | 
|   |  | 
| 1 |   | ten-ounce whole boneless and skinless chicken breast  | 
|   |  | 
| 2 |   | teaspoons toasted sesame oil  | 
|   |  | 
| 2 |   | cloves garlic, minced  | 
|   |  | 
| 1 |   | small onion, cut lengthwise into 1/4-inch-thick slices  | 
|   |  | 
| 4 |   | ounces shiitake mushrooms, stemmed and sliced 1/4 inch thick  | 
|   |  | 
| 2 |   | carrots, peeled and cut into matchsticks  | 
|   |  | 
| 1 1/2 |   | teaspoons grated ginger  | 
|   |  | 
| 1 |   | teaspoon freshly ground black pepper  | 
|   |  | 
 |   | Pinch cayenne pepper  | 
|   |  | 
| 1/2 |   | teaspoon salt  | 
|   |  | 
| 3 |   | tablespoons cornstarch  | 
|   |  | 
| 3 |   | tablespoons low-sodium soy sauce  | 
|   |  | 
| 6 |   | tablespoons rice-wine vinegar  | 
|   |  | 
| 1 |   | large whole egg, plus 1 large egg white, beaten  | 
|   |  | 
| 3 |   | large scallions, trimmed and cut crosswise into 1/4-inch-thick slices  | 
|   |  | 
| 6 |   | ounces firm or extra-firm tofu, cut into 1/2-inch cubes  | 
|   | 
|   | 1.   In a small saucepan, bring 3 cups chicken stock to a boil. Add chicken breast; poach until cooked through, about 12 minutes. Transfer chicken to a cutting board; slice in half crosswise, then into 1/4-inch-thick strips. Set aside. Pass stock through a cheesecloth-lined sieve set over a medium bowl; set aside.  | 
|   | 
|   | 2.   In a 6-quart saucepan, heat oil over medium-low heat. Add garlic and onion, and cover. Sauté, stirring occasionally, until translucent, 6 to 7 minutes. Add mushrooms, and sauté until tender, about 5 minutes. Add reserved and remaining chicken stock, carrots, ginger, black pepper, cayenne, and salt; bring liquid to a boil. Reduce the heat, and simmer until carrots are tender, about 3 minutes.  | 
|   | 
|   | 3.   Place cornstarch in a small bowl, and slowly whisk in soy sauce until cornstarch has dissolved. Whisk in vinegar. Slowly whisk cornstarch mixture into soup. Simmer until soup is clear, 5 to 7 minutes. Add reserved chicken, and continue simmering until chicken is heated through, about 2 minutes. Turn off the heat.  | 
|   | 
|   | 4.   Slowly pour beaten eggs through a perforated spoon into soup. Cover soup, and let stand 1 minute. Remove the cover, and gently stir. Add scallions and tofu. To serve, ladle into individual bowls.  |
