You can give canned broth more flavor by a simple simmering process. Add 1 quart of canned chicken broth to a large saucepan. Add 1 large chopped onion, 1 chopped stalk of celery (with leaves), 1 chopped carrot, and a few sprigs of parsley. Heat until lightly steaming. Reduce the heat and simmer for 30 minutes. Strain through a colander. Use in soup and sauce recipes.
