The original recipe calls for a full 2oz (60ml) bottled-in-bond straight rye (without the optional extra splash of water to help with dilution). Just 1/3oz...
Intriguing flavors. In my eyes, one of the more worthy showcases for apricot liqueur. I first tried this with Rittenhouse Rye, Giffard Abricot du Roussllon, and Noilly Prat. Something was missing. A few iterations later, I subbed Dolin Blanc for the vermouth (and Willet Pot Still Bourbon for the rye), without adjusting any specs, and that was the one.
I still love this cocktail, but I’m always interested in riffs. Tonight I tried it with applejack, dry vermouth, and Belle de brillet pear liquor. Cardamom bitters, if you have it.
