Beginning in the mid-1970s, Pépin reinvented himself as an educator, author and eventually a television personality. Pépin worked as a consultant for restaurateur Joe Baum on his Windows on the World project, and offering classes at small cooking schools and cookware shops around the United States. In 1976, Pépin authored his cookbook "La Technique", followed by "La Methode" in 1979. The use of thousands of photographs, illustrating the techniques and methods required to achieve certain culinary results, provided a window into the art of cooking. The books are credited by chef Tom Colicchio and others as helping them to learn the craft of cooking.
