104. Coronation Cocktail

 My interpretation:
  0.75 oz Noilly Prat Extra Dry Vermouth
  0.75 oz Hawthorn’s London Dry Gin
  0.5 oz Dubonnet

Stir with ice, strain, serve. — This cocktail appears in the 3rd Edition, JM 1910, calling for equal portions and “orange gin” rather than dry gin, as it appears in Straub 1913:

The change in proportions may have been for finer balance of the palate, or perhaps to conserve an increasingly rare Dubonnet. The name and year suggest this was created after the death of Edward VII in preparation for the coronation of George V, but it may have been for Edward VII’s coronation in 1902.
