• Keeps the food warm for a long time. The porous nature of clay helps to keep the food warm for an extended period after cooking.
• Keeps the food from becoming stale soon. Foods tend to stay fresh longer in clay pots due to their natural cooling and moisture retention properties.
• Alkaline property in the pot neutralizes the acidic property in the food. Clay is naturally alkaline, which can help balance the pH of acidic foods, making them healthier and tastier. This also means food tastes great without much effort.
