Hot and Sour Chinese Soup
In a soup pot, mix together the broth, soy sauce, mushrooms, bamboo shoots, and pork. Bring to a boil; reduce the heat and simmer for 5 minutes. Add the tofu, pepper, and lemon juice; bring to a boil.
Whisk together the cornstarch and water until smooth; add it to the soup and boil, stirring constantly, until it thickens slightly. Reduce heat and stir the egg into the broth. Remove the pot from the heat; stir in the sesame oil and sprinkle with scallions.
This traditional Chinese soup can also be made with chicken or beef.
