Marcella Hazan, a pioneer of Italian cuisine, died yesterday at 89 years old in Longboat Key, Florida. She introduced Americans to the art of simple and authentic Italian food in an era when such culinary concepts were undervalued. Whether you are aware of her contributions to the food world or not, much of what we know and understand to be true Italian cooking is because of her. This lemon roasted chicken is a testament to her cooking philosophy - simple good food. She will be missed.
