I mixed up my dough on a Thursday evening (using my standard recipe from Bittman's How To Cook Everything Vegetarian), and then placed it in a covered bowl in the refrigerator. On Saturday afternoon, I came home, peeked into the fridge, and saw that the dough had risen nicely. The pizza was in the oven about 20 minutes later. Ten minutes after that, I was marveling at how much better a pizza crust that's rested for a couple of days really is. And not just because I was pleased to be eating a freshly-baked homemade pizza about a half-hour after I walked in the door (although that was nice, too).
The flavor and texture of the crust were lighter, even though it was the same recipe that I normally use. (The NYT used the word "nuanced" to describe the change in flavor, which sounds silly when applied to pizza crust but is, I think, accurate). The only downside is that I ate much more pizza than I normally would, because I kept wanting to "confirm" the difference.
