At 24 inches in diameter, this 15-pound loaf is big enough to serve a crowd, and built to impress. It has a mildly sour taste, a rustic texture, and a thick crust that helps keep the bread from drying out. (After the party you can freeze what's left, cut into serviceable hunks.) Order it undecorated, or have us spell "Happy Holidays" or your own message out in dough!
