Mix sugar cube, bitters and a splash of club in a lowball glass. Drop in an orange wedge. Muddle into a paste. Pour in Whiskey and Luxardo, fill with crushed ice, top off with sour and stir. (Garnish w/ a cherry if you're feeling "sconie")
It's easiest to pre-batch the homemade sour mix: 1 part lime, 2 parts lemon, 2 parts simple
Showcasing the phenomenal flavor profiles of both the Kinnickinnic Whiskey and the Fee Brothers Rhubarb Bitters, this is a reinvigorated version/combination of the tried and true Old-Fashioned and the Whiskey Sour.
*Although the amount of Rhubarb Bitters may seem high, the Fee Brothers bitters are really more of a flavoring component, not a bittering agent, so they impart a much lighter and true to name flavor
