Harry of Ciro's ABC of Mixing Cocktails by Harry of Ciro's (1923, p.71) — Harry of Ciro's 1923
| 1 teaspoonful | Cointreau | base |
| 0.5 glass | Amer Picon — Amer. Picon | modifier |
| 0.5 glass | Dubonnet | modifier |
- Shake well and strain into cocktail glass.
This matters because it preserves a small bitter-orange aperitif branch built around Amer Picon and Dubonnet in London 1923.
The drink is structurally valuable because it treats modifiers as the whole drink rather than seasoning a base spirit.
