That’s the magic of rice cooker technology! However, there really are no secrets when it comes to how rice cooker systems actually work. On the whole, rice cooks perfectly based on temperature, and when left to cool. You can expect a rice cooker to shut down after some time, particularly when a specific temperature is reached after, say, 10 minutes. However, depending on the amount of rice in the cooker, you may have to wait as long as 30 minutes to yield a complete meal. Providing you wash the rice or rinse the rice first with water, and providing you close the lid when you’re ready to start cooking, there’s nothing to say you can’t leave your rice cooker to start cooking. If you’re worried that if you leave your rice alone for too many minutes after the rice is cooked to perfection, then you should make a point of looking for a keep warm setting. This common one pot function will ensure that your dish is kept nice and hot while you tend to other dishes. While cooking, let your rice cooker take care of the finer grains – you can trust us on this!
