Instead of using day old rice (coz that would mean you have to wait for one day to eat...and I want it NOW!!), instead boil the rice fresh, place it outside uncovered and spread out a bit in a big bowl/plate for about 15 mins and then dump it in the freezer for about 15-20 minutes.
When you remove it out, it will be cold and no longer sticky and perfect for friend rice. Of course it's not very efficint for your freezer to have a hot plate of rice in there, but thats why you keep it out for a while.
