In a mixing glass, add half the whisky, maple syrup, cherry juice and bitters.
Fill with cubed ice and stir.
Add the rest of the whisky, and keep stirring, adding more ice until the drink is diluted to taste.
Strain into a chilled rocks glass over a large single cube of ice and garnish with a thin piece of orange zest, rubbed over the glass and three cherries.
Optional garnish of a couple of squares of dark chocolate.
