It took a trip to Italy for the 19-year-old Nigella Lawson to discover who she really was:Â an Italian soul in an (imposingly tall and chic) English body. That, at least, is the premise behind her newest cookbook, Nigellissima (Clarkson Potter, $35), released two weeks ago in the U.S. The cookbook author, who also happens to be one of the judges on The Taste, came to Chicago last week for a quick book tour of the Midwest. And figuring that she'd probably had enough questions about Anthony Bourdain and TV in general, we stuck to talking about the universal love for Italian food, and how going to Italy at an impressionable age literally changed her life and made her the single-named star she is today. You can't hear the rounded, brandy-voiced tones and precise diction with which she answered our questions, but her warm affection for the subject of Italian food and culture comes through even in cold type.
