After reading Difford's recipe & Brother Cleve's, I chose some ratios for this cocktail based on my tinkering with other drinks where I liked the ingredients but knew it was going to be too sweet for me. I used 1.5 Elijah Craig Bourbon .25 Rittenhouse rye .5 St. Germain Elderflower liqueur .5 John D. Taylor's Velvet Falernum .5 Lime juice & 2 dashes Peychaud’s bitters served up in a coupe. I'll reduce the Falernum to 1/3oz next time. The suggestion of Rye by Simon made this one to make again.
