So, a Martini that's more than itself but still identifiable as itself? Like a really good cover version of a song! Anyway, on with the show.
1 oz dry vermouth
1.5 oz dry gin
0.5 tsp creme de cacao
Stir well with ice. Strain in to a chilled coupe. No garnish.

(Had I not watched myself add the cacao I don't know that I'd have noticed it in the drink. As it was I could tell there was… something but couldn't quite place it.)
There you have it. No juice. No bitters. No garnish. Taxi cab interior and a big block… and a kitschy air freshener.
