The following formula is for one cocktail only; the same proportions must be observed in making any number of them. Have the glasses well chilled before beginning, and always use sugar syrup instead of sugar for sweetening.
Enough cracked ice to chill but not to dilute. Stir with a spoon until thoroughly chilled and blended. The mixture must not be shaken, as that fills it with air. Lastly, take a piece of lemon zest the size of a ten-cent piece, hold it over the cocktail, and express a little of the oil, then drop it in the glass.
