One of the greatest pizza hacks is that when you want to warm up the leftovers, do it in a skillet on the stove — not in the microwave. The crust will crisp and your slices won’t be soggy. Here’s another pizza hack: the next time you order a delivered pizza, order it uncut. When the pizza place cuts it, all the juices run down to the cardboard and make the crust soggy. Just after you order your pie, fire up the oven. Throw your pizza stone or sheet or whatever in there and set the temp to 220 degrees. When the pizza arrives pop it in the oven for a bit to get it hot, then remove it and slice it.
