The premise is that you mix up the large batch of dough (which with a stand mixer takes only a couple of minutes), then you refrigerate it. Then, whenever you are ready to bake, you cut off a hunk of dough, shape it, let it rest, and the bake it off. The dough recipe is designed to get more flavorful as it is in the fridge, and the other steps really do only take 5 minutes. (Of course, the rising takes a while and the baking as well, but you can do other things while those are going.)
Here's the dough blob in my refrigerator bowl. The amazing book is in the background.
Once you cut off the hunk of dough, you shape it (and for some of the other recipes you add in other spices, toppings, etc) and let it rest on the peel:
Then, after it is risen, you bake it on a stone with a steam bath. What you end up with is a gorgeous final product with the perfect crusty outside, and delicious chewy inside. A-MAZING!
Of course, it only took us 5 minutes to eat it too. Here's where you can order the book:
