Ruhlman, Michael. The Book of Cocktail Ratios: The Surprising Simplicity of Classic Cocktails. Illustrated by Marcella Kriebel. New York: Scribner, 2023. Supplied ebook-derived PDF, 282 pages; ebook ISBN 9781668003411.
Five families provide Ruhlman's teaching framework, with highballs and exceptions added. His preference change after a wife-administered shaken/stirred Margarita comparison is a personal anecdote; the book does not describe randomized, independently repeated, proof- and temperature-matched testing.
