This rice cooker is a piece of specialised microwave cookware. Its 2-layered design allows the vitamin-preserving preparation of rice which then can be kept warm for hours after cooking. To wash the rice, the inner container is filled with water, which, thanks to the holes in the bottom of the vessel, can be fully drained afterwards. The required amount of water is then filled into the white vessel using the measuring cup. Finally, the rice cooker is closed and placed into the microwave.
