As the origin for the leap day cocktail is rather clear, we don’t see a ton of variation. Slate’s version is by the far most different, opting for an increased quantity of lemon juice. Savoy Stomp’s quantities aren’t actually different, they instead opt for precision of the original’s quantities. 2/3 of the glass measurement used in the the original book is approximately 1/2 of 3/4 of an ounce. For you fraction addicts out there, 3/8 of an ounce will do.
Happy Leap Day!
