Fill a glass with ΒΌ part water and add fresh cranberries into the water.
Place a sprig of rosemary in the center of the glass to resemble a lit Christmas tree.
Freeze the glass so the cranberries and rosemary stay at the bottom of the glass.
In a shaker filled with ice cubes, add the following:
– 2 cl Black Barrel
– 4 cl cranberry juice
– A small splash of lemon juice
Pour the cocktail into the prepared glass and top it off with Sprite.
Enjoix!
