3/4 oz Sweet Vermouth (Vya)
3/4 oz Dry Vermouth (Noilly Prat)
1/2 oz Lemon Juice
1/4 oz Simple Syrup
Shake with ice and strain into a cocktail glass. I double strained and added a lemon twist.
On Thursday, I spotted the X.Y.Z. in Robert Vermeire's Cocktails: How to Mix Them and the description of "this cocktail is made exactly like the Bronx, but lemon juice is used instead of orange juice, and a little plain syrup or gomme is added to sweeten the cocktail" made me think of the citrus variation in Satan's Whiskers I had earlier in the week. The text distracted me from realizing that I was about to prepare a Perfect Martini crossed with a Gin Sour, and indeed, I was curious as to what a sweetened-lemon Bronx would be like. There is another X.Y.Z. cocktail that appeared a few years later in The Savoy Cocktail Book which I have had before; that one is essentially a rum Sidecar and is well worth trying in its own right.
