Turtle Bread knows crust: the splinteringly crisp but tender crust of a baguette, the soft shell of a potato loaf, crackling and toothsome ciabatta. Turtle also knows crumb: airy baguettes, soft and open hearth loaves, dense brioche. What's amazing is that, like a batter in a cage hitting ball after ball out of the park, Turtle Bread makes nearly three dozen unique breads, consistently producing excellent loaves. Most of them are set apart not by futzy seeds or olives, but by masterful manipulation of the same four basic ingredients: flour, yeast, water, and salt. But, while the ficelle, levain, campagne and other classics are remarkable, the chocolate bread alone, an Italian-inspired yeasty loaf with the emphasis on the cocoa, not the sugar, deserves its own special award.
