Because rice can take quite a while to cook,(and not everyone likes the taste of quick 5 minute rice) you will be happy to know that you can freeze rice .

Cook your rice as usual.
Allow to cool, then PLACE IN THE FRIDGE.
After the rice is chilled in the fridge, transfer rice to freezer bags or containers, and freeze as usual.( Allowing the rice to chill will avoid the problem of mushy rice when you thaw it)
