Millie marinates the chicken in egg white for an hour to help keep the meat juicy when it is cooked. Sometimes she substitutes tofu for the chicken, browning it in a wok.
Marinate chicken slivers in egg white for 1 hour. Heat oil hot (375 degrees F in an electric wok or skillet) and quickly stir-fry chicken slivers about 2 minutes. Lift out of oil into a dish and cover. If necessary add another tablespoon of oil and heat the skillet again. Put in the snow peas and mushrooms, and stir-fry 3 to 4 minutes, then add sugar, salt, wine, and 1 cup of the broth. Bring to a boil and add cornstarch dissolved in remaining ½ cup broth. Boil again, add chicken, and serve.
