Rich Simple Syrup
Simple syrup at a 2:1 sugar-to-water ratio rather than the standard 1:1. Thicker, sweeter per volume, and more structurally consequential in cocktails. Required by name for the canonical Mai Tai and many other classic exotic-cocktail builds.
Standard simple syrup is 1:1 by volume—one part sugar dissolved in one part water. Rich simple syrup is 2:1—two parts sugar to one part water. The difference sounds small and tastes structural.
Why the ratio matters
- A 1:1 simple syrup has roughly the same viscosity as water. It integrates instantly when shaken; it also adds significant volume to a cocktail.
- A 2:1 rich syrup is noticeably thicker—closer to maple syrup than water. It adds less volume per measure of sweetness, so less rich syrup is needed to balance a drink than 1:1 simple. The lower volume preserves more of the drink’s other character.
- The thicker syrup also brings a slight textural difference to the finished cocktail. Slight, but detectable.
Many exotic-cocktail recipes specify rich simple or 2:1 simple by name. The canonical Mai Tai is the headline example—Trader Vic’s 1944 recipe calls for 0.25 oz of rock candy syrup (a related super-rich sweetener) and modern reconstructions translate that to 0.25 oz of rich simple. Other recipes calling for it include the Daiquiri (Constantino Ribalaigua’s El Floridita proportions assume rich), the Hemingway Daiquiri, and many others.
The sugar you use matters: white sugar produces a neutral rich simple, demerara sugar produces a rich demerara syrup, turbinado is in between. Many recipes specify which to use. When in doubt, white sugar is the safe default.
