3/4 oz Drambuie
1/2 oz Pimm's No. 1
1/4 oz Balsamic Vinegar
1 dash Bittermens Mole Bitters
Stir with ice and strain into a cocktail glass. Garnish with a lemon twist.
For a second drink at Scholars, I narrowed it down to two drinks I was curious about, and bartender John Henderson recommended the Scarlet Letter for it was the more dynamic of the duo and changed over successive sips. The drink may have been a Nathaniel Hawthorne reference especially given the subtitle, "deep red, the addition of balsamic could be considered taboo." While I have had vinegar-based shrubs as cocktail ingredients, I have only been served one other drink, the Averna Pineapple Shrub, that used vinegar as a mixing ingredient. And I did tinker with it in the Casper Sour. With the honey liqueur being the main sugar source in the Scarlet Letter, perhaps this was an instant Drambuie shrub.
