Beef Noodle Soup

In bowl, combine steak, half each of the cornstarch, soy sauce, and sherry (if using), the oil, five-spice powder and sugar. Let marinate for 15 minutes.

Meanwhile, cook noodles according to package directions; drain and divide among 4 bowls. Peel carrots; cut into thin 2-inch (5 cm) long strips. Separate bok choy into leaves. Set aside.

In large Dutch oven, bring stock, remaining soy sauce and sherry and 2 cups (500 mL) water to boil. Stir in steak mixture, separating with spoon; reduce heat and simmer

In small bowl, whisk remaining cornstarch with 1 tbsp (15 mL) water; stir into soup and simmer until glossy and slightly thickened, about 2 minutes. Return soup to boil. With fork, stir in egg in slow thin stream, pulling into strands. Pour over noodles; sprinkle with green onions.
