It's not too late to enter our holiday iPad giveaway — beef up your kitchen prowess with a 32-gig iPad and a 75-title e-cookbook library from Clarkson Potter and Ten Speed Press. Among the digital editions is Momofuku, David Chang and Peter Meehan's extraordinary culinary chronicle of Chang's Manhattan restaurants — at the very first, Momofuku Noodle Bar, they serve noodles with a ginger-scallion sauce that Chang calls "one of the greatest sauces or condiments ever. Ever."
