Generally, yes. This is because the average modern rice cooker will have safety functionality, allowing you to keep your cooked rice warm once it’s finished cooking. When you cook rice in a rice cooker, you are essentially leaving your system to do its business – meaning that it will turn off when it’s done. This is a fantastic function to make a point of looking for, and even some of the most basic one pot options offer it as standard! However, you might want to consider whether or not this type of function is the best to invest in. There is the argument that the longer you leave rice on keep warm, the more flavour you are going to lose. This is regardless of whether you are using a 3 cup rice system, a 4 cup rice cooker or otherwise. It’s also regardless of how much water you put in your measuring cup, too. Yes – it’s great to have a rice cooker that takes care of itself as well as your rice! However, whether you cook 1 cup rice or 2 cups of rice, you’re going to want to put safety first. If you really want to be careful, make a point of shutting down your rice cooker at the wall before you go to bed. Always read the rice cooker manual and listen to what the manufacturer has to say.
