Recipes are practitioner examples, not a controlled compatibility matrix. Rock-and-rye is already flavored/sweetened. AlpineSlide's vermouth280, Bjorn's shake/stir wording310 and ItalianBuck's carbonated shaking372 need operational clarification.
Modern cocktails280–442; Gobis311; Levy404–405; SharpieMustache412–413
The full modern chapter specifies base spirits, amari, syrups, acids, garnishes and methods. Gobis and Levy recommend learning ingredients separately and in combination. Recipes demonstrate modifier roles including sweetness, bitterness, aroma and body; an ingredient swap changes more than flavor alone. Elford recommends blind tasting and restrained additions, without specifying a complete validation protocol.
