Freezing cooked rice

Don't do it. Rice can be really dodgy. And it's pretty cheap so if you have over cooked it just throw it away and remember to do less next time.

Unless it's been specially treated [as used in chilled meals]it must be binned. I used to cook rice meals and re heat them until I read otherwise.

I do know a local Chinese restaurant were prosecuted for serving re-heated rice .
Maybe that helps , I would be loathe to do it myself .
