Wisconsin Cheese Soup

Directions

In a large heavy kettle, melt butter or margarine; add carrots, celery, onion, green pepper, mushrooms and ham (if desired).

Cook over medium heat until vegetables are crisp and tender, about 10 minutes, stirring occasionally.

Do not brown. Add flour and cornstarch; cook, stirring constantly, about 3 minutes.

Add broth and cook, stirring, until slightly thickened.

Add milk, paprika, cayenne and mustard.

Stir in cheese gradually, stirring until cheese is melted.

To avoid curdling, do not allow soup to boil after cheese is added.

Season to taste with salt and pepper. Serve piping hot.

Makes about 2½ quarts soup.
