The Cocktail Spirit with Robert Hess
The Widow's Kiss dates back to around 1895. This was during a time when a "new" age of cocktails were coming into existence as bartenders were letting it expand beyond it's previously held definition of "spirits of any kind, sugar, water, and bitters". They were experimenting with the use of vermouth (and hence the Martini and Manhattan), as well as various herbal liqueurs which would have previously been simply sipped neat. The Widow's Kiss doubles up on it's elixir content by using both Chartreuse and Benedictine. If you can only find green Chartreuse and not yellow, you can substitute if you cut back by about a third.
2 oz Calvados
