Ok, so this may sound dumb -- but I never knew that there was something wrong with reusing dried beans or rice that I use to line tart and pie shells for blind baking. I was just watching Ina Garten and she mentioned that they become inedible after they are used for blind baking. Is this true for beans AND rice, and if so, why? I literally JUST made hummus with some dried chickpeas that had been blind baked at least several times...nothing seemed problematic to me. Should I be worried?
