347. Trowbridge Cocktail

My interpretation:
  1 oz Castle & Key London Dry Gin
  1 oz Martini & Rossi Sweet Vermouth
  1 dash Regan’s Orange Bitters

Fill mixing-glass half full with ice, stir, strain into whisky glass, garnish with orange twist, serve. — This Sweet Martini with a twist, served down, first appears in Straub 1913 in a 2:1 ratio, sweetened up to 1:1, as usual, when copied by JM1916. There is no mention of ice, so a legitimate form of this drink would include a direct pour, esp. if the vermouth is duly chilled.

345. Treasurer Cocktail

My interpretation:
  1.5 oz Castle & Key London Dry Gin
  0.5 oz Noilly Prat Extra Dry Gin
  1 slice orange (for mixing)

Fill mixing-glass with broken ice, stir, strain, garnish with orange twist, serve. — This strong dry martini with an orange twist appears in Straub 1913 by the slightly different name Treasury, with an orange slice instead of twist, to be shaken (frappéed) with the other ingredients. I have included the orange component on both ends for the added distinction from other similar recipes.
