This book was a spin-off from an "Observer" series. Its two authors, Grigson and Anne Willan of La Varenne cookery school in Paris, augmented their "Observer" articles for the book. Willan's sections, occupying the majority of the 300 pages, give technical advice on various aspects of cooking, such as boning, making choux pastry, the use of gelatine, and cooking with bains-marie. A 1991 bibliography describes Grigson's section—a 47-page "Anthology of French cooking and kitchen terms"—as "an alphabetic listing of descriptions written in condensed but detailed prose, full of personal observation; almost a little book in itself".
