In pondering Lemon Hart Rum's Colonel A.R. Woolley's Improved Planter's Punch presented by Jeff Berry in his Potions of the Caribbean book where the traditional drink was augmented by cooled tea as the weak element, my mind drifted to figure out a good riff on that. I landed on a mashup of the Rum Negroni-like Right Hand as the second recipe point, and merging together the two concepts and including my choice of mint and nutmeg garnishes that I opted for in the Improved Planter's Punch, the Right Handed Planter was born.
2 oz Aged or Black Jamaican Rum
3/4 oz Sweet Vermouth
3/4 oz Campari
1 1/2 oz Black Tea, a strong steep, cooled
1 oz Lime Juice
1/2 oz Sugar
3 dash Mole Bitters
Dissolve the sugar in the lime juice and cooled tea. Shake with ice, strain into a rocks or Collins glass with fresh ice, and garnish with a mint sprig and freshly grated nutmeg.
