Chill the Old Fashioned Glass in advance to ensure optimal serving temperature.

Combine the Highland Scotch, Islay Scotch, Drambuie, and a few dashes of Angostura bitters in a mixing glass.

Fill the mixing glass with ice and stir gently until the mixture is well-chilled and slightly diluted.

Strain the mixture into the pre-chilled Old Fashioned Glass.

Garnish with a fresh twist of orange peel, expressing its oils over the drink before placing it in the glass.
