In their most basic form, rice cookers do exactly that – they cook rice! While they don't necessarily speed up the cooking process, they certainly make it easier. All you have to do is measure the rice, add water, and set it to cook. At the end of the cooking period, some of the water will have been absorbed by the rice, while the rest will have boiled off. Once this has occurred, the unit will either switch to "warming mode" or will simply turn off. Rice cookers can also be used to cook hot cereals, desserts and steam vegetables.
