This is a glass-lidded rice cooker from Hario. The pot is Banko-yaki. Soak rice for 30 minutes → Cook over medium heat for 7-10 minutes → Let the whistle sound, then cook for 1 minute → Turn off the heat and steam for 15 minutes No need to adjust the heat when cooking rice, so anyone can cook delicious rice. It's a user-friendly design that lets you know with a whistle, even without using a timer. I no longer need it because I'm upgrading to a larger size. It was used for about a month. If you'd like to try cooking rice in an earthenware pot, please consider this.
