Canadian Cocktail

On this date, we enjoyed a 'Canadian Cocktail', which was a tasty drink, if you like whiskey as I do.  Worth a repeat.

The recipe per drink (from page 55 of Mr. Boston's Official Bartender's Guide from 1985):

1 1/2  oz Canadian Whiskey (I used Crown Royal)
1 dash Bitters
1 1/2 tsps Triple Sec (LeRoux)
1 tsp Powdered Sugar

Shake with ice and strain into cocktail glass. I garnished with an orange slice.
