Add the ice, whiskey, mango nectar, freshly squeezed lime juice, and coconut cream into a cocktail mixing glass or shaker.
Using a mixing glass, use a long-handled bar spoon and mix thoroughly for thirty seconds.
Also, if you use a cocktail shaker, secure the lid and shake vigorously for thirty (30) seconds. 
After mixing, strain the cocktail into a rocks glass filled with cranberry ice cubes.
Garnish with a wedge of lime and a sliver of mango peel. Cheers.
