Shake one round without ice and one round with ice, strain into a double old fashioned glass with crushed ice, and garnish with mint sprigs.
Perhaps 1 oz each of Malört and Bourbon would work well here too for a slightly less bitter-herbal balance or adjust to your preferred bitterness level.
After seeing the recipes for the Port Light and Starboard Light in Trader Vic, I became inspired. For some reason, I decided that instead of whisk(e)y, what if I were to replace the spirit with Malört? I might have made the connection when I misremembered making a riff of Nick Jarrett's Prizefighter that included Malört and passion fruit; in the end, those were two different drinks: the Cutman and the Cornerman, respectively. For a name, I was considering the Nordic Light akin to the Nordic Toddy, but the Northern Lights seemed rather nautical especially for boats a bit further north.
