Winter Soup features Baby Bok Choy and Corn

Last night I made this soup and also some corn bread. It warmed us into the whole evening. The recipe for the soup:
In 3 quarts of cold water place
3/4 cup Shitake mushrooms, sliced
3/4 cup large dice white onion
3/4 cup celery cut into 1″ pieces
1/4 cup carrots peeled and cut into 1″pieces
1 tspn black peppercorns
1 garlic clove
1 bay leaf
1 strand of Rosemary or 2 of thyme
Cover and bring the water to a boil. Then simmer slowly for 45 minutes.
Add
2 medium size red wax potatoes cut into 2″cubes
1 onion, quartered
2 corn husks, cleaned and quartered
1 cup carrots peeled and cut into 2 inch pieces
1 cup celery cut into 2 inch pieces
2 teaspoons salt or less (or a little more) depending on your want.
Simmer the soup for another 45 minutes uncovered so that the liquid reduces by approximately 25%.
Add 4 to 6 baby bok choy during the last 15 minutes of cooking.
Serve with slices of corn bread, recipe in this blog. Enjoy.
