Saucepans are a type of cooking vessel that are used to prepare sauces, soups, and other liquid-based dishes. They are typically made of metal, such as stainless steel, and have a flat bottom and two handles. Boilers, which are also known as double boilers, are similar to saucepans but have a lid and a larger capacity. POTS are larger than saucepans and are used for boiling or simmering food. They usually have a lid and two handles.
