Condensed soup is a type of soup that has had a significant amount of water removed during the cooking process. This results in a thick, concentrated product that can be easily stored and transported. To prepare condensed soup, consumers typically add water or milk before heating it, restoring its original consistency and flavor. First popularized in the early 20th century, condensed soup became a staple in many households due to its convenience and long shelf life. Brands like Campbell's are well-known for their variety of condensed soups, which include flavors such as chicken noodle and tomato.
