Hot and Sour Soup

Becky wants these recipes which come out of my brain only, not my recipe box. These quantities are not for publishing, but for adjusting. Happy cooking.

In one or two quarts chicken broth, cook some pork. Remove and cut into small slices, return to broth. Add 1/2 cup soy sauce and 1/4 c white vinegar, 1 tsp or more black pepper, 1 can drained bamboo shoots (if you like the flavor, you can add the bamboo shoots water to your soup), one box of smooth tofu cut into bite sized pieces. Thicken as desired with cold water and flour or cornstarch. Serve with chopped green onions.
