As fulfilling as it can be to raise and nurture children, there comes a time when they grow away from their parents. Journalist Jan Wong saw this happening in her own family, and tried to make the most of it. Her new book, "Apron Strings: Navigating Food and Family in France, Italy, and China," is the result of taking her son, Sam, on a culinary journey. The Agenda in the Summer welcomes Wong to discuss her book and its genesis.
