I was inspired by Trader Sam's Nautilus during the Instagram "Tiki the Snow Away" event in January 2020.
1 oz Dark (or Aged) Jamaican Rum
1 oz Rhum Agricole Blanc
1 1/2 oz POG Juice (** see below)
1/2 oz Lime Juice
1/2 oz Ginger Syrup
1/2 oz Maraschino Liqueur
2 dash Angostura Bitters
Whip shake with crushed ice, pour into a Tiki mug, fill with crushed ice, and garnish with freshly grated nutmeg.
(**) POG Juice is equal parts (or here 1/2 oz each) passion fruit nectar, orange juice, and guava juice.
