You must master the rice cooker, especially if you've never used one before. It requires some time, but when you've learned how you can set it up and let it cook rice, you don't have to keep an eye on it, as you would when boiling rice at the stove.
A few people soak their basmati rice prior to cooking it. It is due to the belief that this rice has a very high amount of starch. Some even triple wash the rice prior to taking it to soak. This results in more firm rice. However, some prefer sticky rice. If you love sticky rice, then you can skip the washing and soaking. Start cooking immediately.
