Cornmeal was never MY friend, nor that of my son.
And we don't have room around here to keep a stack of parchment paper when you buy in the economical large packs used by bakeries, and I won't pay the exorbitant cost for the smaller packages sold by kitchen specialty shops. Plus, the stuff has a tendency to get soggy. Plus plus, I don't care what people say, it makes me nervous when the stuff turns black - or at least dark brown - in a really hot oven.
Then I discovered SUPER PARCHMENT - reusable parchment. I still have the original super parchment (google it, you'll find it) which is over 2 years old now and definitely showing its age, but still perfectly usable. I have since graduated to Pan Pal pan liners, which are easily found at the webstaurantstore.com. It comes in 2 sizes, The smaller size is a little too small for the size pizza I usually make. The larger size can be cut to fit your baking stone. It's much heavier duty than the Super Parchment so I expect it to last even longer. You must not fold it or cut on it (it is after all a parchment-like substance). I roll mine up and keep them in a paper towel roll. If that's too down-homey for you (Use it up, wear it out, make it do or do without!) you can buy a scrap piece of PVC pipe and use that as a holder instead. Just wipe it off with a damp cloth when you're done.
I build my pizza on the super parchment/pan liner. I partially roll out the dough, then finish stretching it (I used to stretch it out from start to finish but fatigue and dexterity issues made me look for an easier way). I cover with another pan liner or some plastic wrap to let it rise, then build the pizza right before putting in the oven, slip the paddle under the pan liner, slide the whole thing easy-peasey into the oven. Let it set up for a couple of minutes then pull the pan liner out - lift an edge of the pizza with the peel and just whip the pan liner out of there. The super parchment cooled down fast enough that I could easily do that with bare fingers but the thicker pan pal stuff stays hot enough while in the oven that I use a small cloth or oven pad thingy. Cools right down once it's out of the oven though.
Love that stuff. Turned pizza into a regular thing at our house once we no longer had to struggle with the magical twist of the wrist hold your mouth just right pray to the gods of pizza for mercy ritual, only to end up with the pizza on the stone - and on the back wall of the oven, and the door of the oven, and the floor of the oven, and maybe the floor of the kitchen as well. Cuz I don't care WHAT people say, cornmeal does NOT act like tiny ball-bearings in my house, LOL!
I also cut thin strips of the stuff to go around the sides of my removable bottom cake pans when I make Actually Dutch Dutch Apple Pie or cheesecake - no springform pan muss fuss or bother, I just drop the ring down over a can or smaller cake pan and eh voila, whatever I'm baking pops right out, peel off the liner, and you have perfect looking sides.
Did I mention I love this stuff? LOL!
