Combine, stir with ice, strain into absinthe-rinsed chilled glass.
The parental original "West of Lyons" calls for bourbon (but I prefer rye in this; the spicier, the better) as well as Kina L'Avion D'Or. Subbed sweet/bitter vermouth to accommodate my omission of gum syrup. Also replaced vanilla with cedar notes in outstanding bitters from Vancouver.
A home version attempt at the lovely "West of Lyons" by the brilliant crew at Sessions at the Presidio (SF), but named instead for Truffaut's 1976 gem filmed in Thiers, Puy-de-Dôme. Sounds like Game Set Match.
