Add gin, Yellow Chartreuse, and orange bitters to a mixing glass.
Fill with ice and stir for 20–25 seconds until well chilled and properly diluted.
Strain into a chilled cocktail glass.
Express a lemon peel over the surface to release its oils, run it around the rim, and drop it into the glass.
The Alaska first appeared in Jacques Straub's 1913 'Drinks' and later in the Savoy Cocktail Book - the ratio of gin to Yellow Chartreuse can be adjusted to taste, with more Chartreuse yielding a sweeter, more herbaceous result. Old Tom gin is a worthy substitute for a slightly rounder, less dry profile.
