The Ideal Bartender by Tom Bullock (1917, p.41) — Bullock 1917
| 4 dashes | Lemon juice (fresh) — Lemon Juice | acid |
| 1 jigger | Jamaica rum — Jamaica Rum | base |
| 1 tablespoonful | sugar — Bar Sugar | base |
| plain soda — Plain Soda | dilution | |
| 3 dashes | curacao — Curacoa | modifier |
- Fill a large bar glass half full with shaved ice.
- Shake well, strain into a tall thin glass, fill up with plain soda, stir gently, and serve.
Ice: Shaved ice
This matters because Bullock preserves a long Jamaican-rum branch with curacao and soda that sits between sour and highball logic.
The final soda top-up is part of the structure, not an optional lengthening note.
