Stir with ice, strain into a cocktail coupe, and garnish with an orange twist.
I was inspired by the Punt e Mes-Amaro Nardini combination in the Carroll Gardens that also appears in a few other cocktails that I have enjoyed. The richness and depth of my Pierre Ferrand Cognac seemed like a great parallel to the way Amaro Nardini comes across in a drink, and from there, I opted for Green Chartreuse as an accent for it teamed up wonderfully with Nardini in the Green Hornet and Key Party, and for chocolate bitters to augment that note in both the Nardini and the Cognac (plus, Green Chartreuse and chocolate are a match made in heaven). Given the two French ingredients, I dubbed this one after one of the first French punk bands, Métal Urbain, whose album was a cult hit at the radio station I worked at in graduate school.
