Soup containers are vessels used to store and serve soup. The most common soup containers are POTS, CANS, and tureens. POTS are four-letter containers typically made of metal or ceramic, and are used to cook and serve soup. CANS are also four-letter containers, usually made of metal, and are used to store and transport soup. Tureens are seven-letter containers, usually made of ceramic, and are used to serve soup.
