Source argument and examples
Danger and Lapushchik treat named bourbons and bitters as meaningful recipe choices, while inviting experimentation. Their ingredients discussion distinguishes syrups' contribution to body and flavor from sweetness alone (printed p. 14 / PDF 28). This is practical judgment, not a measured model predicting the sensory contribution of every bottle.
The honey syrup on printed p. 17 / PDF 31 uses equal volumes of honey and water. The Gold Rush on printed p. 119 / PDF 133 points back to that prepared ingredient. Consequently, recording only a volume of “honey syrup” omits part of the source specification. Equal volumes here must not be silently converted into equal masses or an asserted sugar concentration.
The methods page distinguishes shaking, stirring, straining, garnishing and muddling (printed p. 19 / PDF 33). These are part of the drink specification, not decorative details after the ingredient list. Fixed mixing times in the book are practitioner directions; they are not validated universal endpoints for temperature or dilution.
Researcher synthesis
The recipe has dependencies: a named prepared ingredient can contain a second recipe. A useful record therefore identifies the bottle and proof, modifier product, syrup formulation and measurement basis, method, ice, garnish and serving conditions. This develops the library's versioned-recipe idea into a concrete documentation practice.
Ingredient substitution and recipe optimization answer different questions. To investigate a bourbon substitution, retain the other specifications. To improve a finished drink, allow deliberate adjustments and record them; the resulting preference does not isolate the bourbon's contribution.
Connections to the current library
A cocktail formula must be tuned to the actual whiskey
The actual-whiskey formula note supplies the reason to adjust a drink deliberately; this source supplies specific ingredient dependencies to record.
Cocktail recipes are versioned specifications with provenance
The recipe-provenance note preserves versions; this note explains why the syrup subrecipe belongs to the version.
A cocktail continues to change after it is served
The changing-cocktail note extends the record into serving time and ice, beyond the initial mix.
Course application
Lesson 10 receives a paper exercise about two records that specify the same syrup volume but different syrup formulations. Learners identify what is missing before interpreting any tasting difference. No additional consumption is necessary.
Evidence and scope
Focused review of printed pp. 14, 17, 19 and 119, with rendered checks of pp. 14, 17 and 119. The book supplies practitioner specifications; the comparison exercise is an Academy synthesis, not an experiment reported by the authors. Storage-life and raw-egg handling instructions have not been validated or adopted as course protocols. Full source prose remains local.
