Terrific decoding of the many regional and global styles of crusts and toppings. The author's meticulous treatment of homemade doughs and starters had me buying brewer's malt to feed the yeast in a very slow, cold "poolish" starter—worth the trouble. The American section has everything from deep dish to cracker crust.
