Callahan's Painkiller

Choose a pre-chilled highball glass.

Prepare a garnish by grating fresh nutmeg.

Combine the cacao and coffee spiced rum, cream of coconut, Monin lavender syrup, pineapple juice, and freshly squeezed orange juice in a shaker with ice.

Shake the mixture thoroughly until well-chilled.

Strain the cocktail into the ice-filled highball glass.

Finish by dusting the drink with the freshly grated nutmeg garnish.
