I know that leftover pizza will only taste remotely good if reheated in the oven, and to add water to rice from your Chinese take-out, but I have to believe that there are other tricks to restoring last night's dinner to some semblance of its former glory. For example, today it was store-bought rotisserie chicken and caramelized brussel sprouts. Had to douse both in sauce and butter to make them remotely palatable. Is there a secret to storage? A magic oven temp? Store it at or bring it to room temp? HELP!
