I have been using a rice cooker to make rice, cous cous, or quinoa for almost every meal I have lately. The rice cooker that I have cooks the rice perfectly, but it always comes out clumpy! I have tried using more/less water, but it doesn't seem to change the outcome. The rice tastes great and seems to be cooked just fine, but it comes out in a huge clump...I could probably stick a knife in the middle and pull out the entire "rice cube" in one piece. Does anyone have any advice as to how I can prevent this, and actually get the rice to not stick together?
