Use for stale (rancid) brown rice found!

Any whole grain will go rancid, meaning the oils in the grain get strong and off-smelling.  It will give the grain itself a nasty flavour.  I don't think it's bad for you and won't make you sick, but it does not taste good.  It tastes awful actually.

In the interests of frugality, I knew there had to be a use for rancid rice whether it was an art project or small animal food. 

You can make a heating pad using rice grains.  Take an old, but not holey (unless you sew the holes shut), clean sock and fill it with rice grains.  Either sew or tie the open end shut.  Heat the rice filled sock in the microwave for 90 seconds.  There, you have a heating pad to apply to muscle aches or to use as a kitten warmer as I currently am.

You can freeze the same rice sock to use for first aid applications.  Reuse it indefinitely.
