How far in advance can I stage pizza?
You can stage pan pizzas (chicago style, or pizza hut style) for up to four hours as long as you keep them covered.  You can stage a stretched dough for up to an hour and a half between two pieces of wax paper.  However, you need to take the time into consideration when proofing your dough so that you don't get blown dough as that will not be delicious.  You should not sauce the crusts or top them as pre-saucing will change how your dough cooks in the oven.  

If the dough forms a harder crust/ dries out, you should consider tossing it as it will not result in good pizza after cooking.
