Aviation
The Aviation appeared in Hugo Ensslin's 1916 'Recipes for Mixed Drinks' and is one of the great pre-Prohibition gin cocktails. Two unusual liqueurs — maraschino and crème de violette — give it an extraordinary pale lavender-blue color and floral, cherry complexity. For years it was made without the violette (it was hard to find), but Rothman & Winter revived domestic production. The violette is non-negotiable — without it you have a gin sour, not an Aviation.
