Hopkinson (Band of Angels, 1998, etc.) documents domestic history in the making, using real people and fleshing out a true, little-known episode. Young Marcia Shaw, considering herself quite competent at household tasks, is considerably annoyed when her expectant mother announces the arrival of a mother’s helper named Fannie Farmer. Not only can Miss Farmer really cook, however, she turns out to be a patient teacher, guiding Marcia past one culinary disaster after another by writing down step-by-step directions, and in the process inventing the modern recipe. For the pictures, Carpenter has transferred, colored, and seamlessly added details to actual 19th-century illustrations, sometimes to hilarious effect: in one scene, for instance, after Marcia is sent to the kitchen to order more biscuits, her supposedly prim and proper mother can be seen through the doorway enthusiastically licking her plate. The tale is presented in episodic “Courses,” framed quotes from Miss Farmer’s now-famous cookbook hang on the wall in many scenes, and an afterword (plus a recipe) follows the triumphant conclusion, in which Marcia proudly navigates a recipe to make an enormous Golden Cake all on her own. Delicious! (Picture book. 7-10)
