Place the sugar cube in the bottom of an Old Fashioned glass and soak with 4-6 dashes (or drops) of Aromatic Bitters. Add a splash of water and muddle the sugar until it dissolves fully in the water and bitters. Only add enough water to dissolve the sugar. Add bitters and water to sugar.
The best way to get an Old Fashioned you like is to perfect your own recipe then instruct the bartender on how to make your. Old Fashioned. This will avoid you being served a Bourbon & Soda when you order an Old Fashioned. Also, ascertain whether the bar has Angostura bitters when you order.
