Well, I've always been a great fan of the Widow's Kiss... described by Ted Haigh in Vintage Spirits and Forgotten Cocktails as being, perhaps, "the most evocative drink ever." Now, in Doc's lays claim to his preferred recipe being as follows: 1.5 oz Calvados .75 oz Yellow Chartreuse .75 oz Benedictine 2 dashes of Angostura, shaken, strained up, garnished with cherry. However, having somewhat provincial taste myself sometimes, and finding, in Philadelphia, a comparable abundance of cheap Laird's Bonded Applejack (as compared to lovely, but very frequently over-priced Calvados) I frequently find myself preferring it prepared as follows: 1.5 oz Laird's Bonded Applejack (100 pf) .75 oz Green Chartreuse (110 pf) .75 oz Benedictine (80 pf) 3-4 dashes of Angostura, shaken, strained up, garnished with cherry. Which makes, in the end, for a drink with one of the highest the overall proofs I would dare to recommend, even after dilution, especially as there's nary a small cocktail glass to be found in the fair city of Philadelphia, and the best bartenders in town tend to bring up the pour while preserving the proportions. Loving, as I do, Lemonhart's 151, I though one night that perhaps a bit of that flavor would make a fine addition to the cocktail. I can't honestly recall whether it did or it didn't: the hangover left me disinclined to repeat the experiment. Cheers. N.
