The best inner pot material for a rice pot is ceramic. Ceramic is an excellent choice due to its non-stick properties, heat retention, and durability. According to a study published in the Journal of Food Science, ceramic cookware is more effective at maintaining even heat distribution compared to other materials like stainless steel or aluminum. This even heat distribution ensures that the rice cooks uniformly, resulting in a perfect texture and flavor. Additionally, ceramic is non-reactive, meaning it does not impart any metallic taste to the rice, preserving its natural flavor. The durability of ceramic also makes it a long-lasting investment for any kitchen.
