For truly delicious rice, the Japanese rely not only on quality rice, water, and technique, but also on this clever little tool. Made with ceramic infused with nano platinum particles, it gently turns water slightly alkaline, allowing moisture to penetrate deep into each grain and bring out its natural sweetness. Simply place it in your rice cooker or electric pot to instantly elevate everyday rice. The donut-shaped design makes it easy to remove even when hot, making rice cooking smarter and easier.
