|Lemon juice||1.5cl 0.5oz|
|Crème de violette||0.75cl 0.25oz|
The ¾-ounce portion of lemon juice is the “hot days” version, a bit more sour and brightly refreshing on sticky summer evenings. Lemons are highly variable, so as you experiment with the proportions, you may want to work in a little simple syrup to balance the flavors without overloading the liqueurs; maraschino and violette can be overbearing, and I’ve found that these relatively small amounts—less than you’d find in many published versions of the drink—work well for both flavor and color. (I haven’t found a drink yet that is improved by adding more than ¼ ounce of Luxardo, it’s fairly strong.)
Some of the citrusy gins make a fun variant in this cocktail, especially if you want to try upping the lemon nose and flavor without pushing up the sourness. I’ve used New Amsterdam and Bombay Sapphire with good results, but there are many to play with.
(Cold Glass has a great piece on the troubled history of the cocktail!)
