The cooked food in clay pot remains moist. As more steam circulates, which helps in cooking, oil usage is reduced. cooking in clay pottery. Research states that clay pottery results in less evaporation rate and the food is cooked deeply and is tastier as compared to cooking in metal utensils.

Such water supports the proper heart functioning and very useful for the sensitive throats. Clay or earthen utensils add back the mineral deficiency of victuals and try to absorb the excess minerals.
