Stir with ice, strain into snifter glass
I used Wild Turkey Rare Breed Bourbon (I didn't have Booker's.) This is a great combination of Maurin Quina and Nonino. They work harmoniously with the bourbon (not unlike my "Devil's Gondolier" which uses Select Aperitivo with Maurin Quina, and no bitters) While I generally don't favor/use Angostura's Orange Bitters unless called out, in this case the latter helps provide a tang that accentuates the Nonino in this recipe--the overall bitters package is a force multiplier here.
