An OLLA is a type of ceramic cookware that is traditionally used in Spanish and Latin American cuisine. It is a round, earthenware POT with a wide mouth and a narrow base, often used to make stews, soups, and other dishes. The word 'OLLA' comes from the Latin word for 'POT, ' and it has been used for centuries to prepare meals. Ollas are also known for their ability to retain heat, making them an ideal choice for slow-cooking.
