Cut 2 pounds of fresh pork into thin strips and let fry ten minutes. Add 1 large onion sliced thin and let fry; then add 1 cup of sliced mushrooms, 2 stalks of celery cut fine, ¼ cup of Chinese sauce and a pinch of pepper; moisten with ½ cup of hot water. Cover and let simmer until tender. Thicken the sauce with flour moistened with a little milk and let boil. Put some well-seasoned cooked rice on a platter, pour over the chop suey and serve very hot.
