My interpretation:
1.5 oz St. George Botanivore
0.75 oz Gallo Dry
0.75 oz Yzaguirre Rojo
Shake with ice, strain, garnish with twisted orange peel. — Essentially what people might today call a perfect Martini with an orange twist. The putative house cocktail of the famous Blackstone Hotel, built in Chicago in 1910, the recipe was included in Chicago-based Straub’s pocket manual and from thence likely came into Manhattan-based Grohusko’s expanded 1916 edition.
