This is simple to make and delightfully complex to taste. This old cocktail rewards experimentation; the different Artisanal Gins made in New England can change the nature of this drink in unexpected ways, and the two "official" variations described below double the possible permutations. 

It's not a strong drink; equal parts of gin and four other less potent ingredients, plus a dash of Orange Bitters is all it takes. That means you can experiment with a few different gins in one sitting while imbibing no more alcohol than a standard restaurant Martini.

There are two variations of this cocktail.  You can get Satan's Whiskers "curled", as written here, or you can get them "straight" by substituting orange curacao for the Grand Marnier.
