Hot-and-Sour Soup

In a large saucepan, heat the canola oil. Add the ground pork, minced scallions, ginger and garlic and stir-fry over moderately high heat until the pork is cooked through. Add the chicken broth and bring to a simmer. Add the tofu, mushrooms, rice vinegar, soy sauce, sugar, Tabasco, pepper and 2 teaspoons of the sesame oil and return the soup to a simmer.

Whisk the cornstarch with 2 teaspoons of water; whisk into the soup. Whisk in the eggs and simmer for 1 minute. Drizzle with the remaining sesame oil, sprinkle with the sliced scallion and serve.
