Earthenware pots, also known as ollas (5 letters) and marmites (8 letters), are traditional cooking vessels made from clay. They have been used for centuries to cook food over an open flame or in an oven. Ollas are typically round with a wide mouth and a narrow neck, while marmites are usually tall and cylindrical. Both types of earthenware pots are excellent at retaining heat and moisture, making them ideal for slow-cooking stews and soups.
