In ancient Persia, kitchens were an important part of daily life, and some incorporated a built-in steam room known as a 'garmabeh.' These steam rooms were used for cooking, as well as for bathing and relaxation. The ancient Persians believed that steam had therapeutic properties and used it for various purposes. The garmabeh in ancient Persian kitchens were typically made of stone and featured a system that generated steam. The steam would then be used for cooking, particularly for steaming rice, vegetables, and meats. It was believed that steaming helped retain the natural flavors and textures of the food. The steam rooms also served as a place for relaxation and rejuvenation, with the steam believed to have cleansing and healing effects. People would often spend time in the garmabeh, enjoying the warmth and steam while taking care of their physical and mental well-being.
