I have this stainless steel cup hanging on the kitchen wall, near the rice cooker on the counter. It holds exactly how much rice I want to cook at any one time. If I have guests I add extra cupfuls. Like most people here, I wash the rice thoroughly in the rice cooker bowl, pouring the starchy, dusty, insecty water away until it is clear. So, I'm effectively washing the rice and the bowl at the same time.
