Chinesse food?

Once again my grandfather is at it. He picked up chinesse food from his neices house, by the look of the rice this HAS to be atleast a week old jus dropped in our fridge today...

Research on the issue: How long can cooked rice stay in the fridge?

Answer

3-4 days, Check to see if water has formed in the container, if it did, don't serve it. ( From wiki answers )

So what happens when the rice is dried up and feels like rocks? -JusSayenTho
