Kurt Timmermeister used to own Cafe Septieme on Broadway, but by the end of his time there, he had a shameful little secret: He would not eat the food at his own restaurant. Financial exigencies had led him to cut food costs, and the pallets of pale, slimy food-service pork cutlets turned his stomach. He sold Septieme and bought a farm on Vashon Island, with very little idea of what the hell he was doing. His new book, Growing a Farmer, tells the great story of how he figured it out.
