After 15 years behind the bar at the five-star luxury Hotel de Russie, Massimo D’Addezio left to open his own cocktail bar, Co.So. Cocktail & Social in Pigneto, eastern Rome’s nightlife epicenter. With the support and skills of London-trained bartender Giorgia Crea, Co.So. does a brisk business of cocktails that are twists on the classics, with cheeky names like the Carbonara Sour. Their version is a fresh and light vodka sour with black pepper and citrus introducing a little kick and the guanciale-washed (fat-infused) vodka lending a mellow savoriness.

Editor's Note
Guanciale-Washed Vodka:
2 cups 80- or 100-proof vodka
1/2 cup rendered guanciale fat
Combine the vodka and guanciale fat in a medium jar and shake well. Place in the freezer for at least 36 hours. The fat should separate and rise to the top. Remove from the freezer, discard the fat, and carefully pour off the vodka through a fine-mesh strainer or several layers of cheesecloth. Store in the refrigerator for up to one week.
