If you're interested in bread baking, there's quite a selection of fine books to guide you into the rabbit hole of the craft — and thanks to the efforts of such great writers and bakers, really outstanding bread can come from home kitchens, given time and effort and technique. However, most of these books approach pizza as, well, just bread shaped differently, with stuff thrown on top. Including Forkish himself, in his prior book Flour Water Yeast Salt.
Here, Forkish — immersed in a deep study of Pizza in Italy — has the revelation. Pizza is not bread. Pizza is it's own unique thing, with myriad traditions and styles across the states, and ALSO across Italy. Getting to the root of making good pizza, then, comes to understanding the style you want to achieve, the ingredients you have available, time, temperature, and technique.
No other book goes into the history and technique of pizza making quite like this. And while the recipes themselves might be more "examples of what one could do, given this style," it's the emphasis on the dough and technique that makes this a winner. I know I'll be regularly referring to it.
