Can I re-use rice if it has been used for blind baking?
I have cooked rice that was used for weighting a pie crust with fine results.  I should have cooked some that wasn't baked to see what the difference was, but in any case it turned out fine.  Of course it may matter what temp the rice was baked at and for how long, and this could also affect the duration needed to cook the rice itself. 

I have also boiled beans that were previously baked, and they turned out fine, too.
