Cookbook

A cookbook, (AUDIO: The Kingmaker) or recipe book, (PROSE: Slow Decay) was a kind of book that gave instructions on how to prepare various meals.

History
By the 2000s, Gwen Cooper and Rhys Williams had a number of recipe books and used them to learn how to cook new dishes. (PROSE: Slow Decay)

Undated events
The Fifth Doctor recalled that his previous incarnation chose to write the Doctor Who Discovers series of educational children's books rather than a novelty cookbook. (AUDIO: The Kingmaker)

Behind the scenes

 * The Doctor's offhand comment that "it was either that or write a novelty cookbook" refers to The Doctor Who Cookbook.
