Irish Godfather

Select and pre-chill an Old Fashioned glass.

Prepare a garnish by twisting a strip of orange zest.

Combine the Irish whiskey, Adriatico Amaretto Liqueur, and Difford's Boker's Style by Bob's Bitters in a mixing glass with ice.

Stir the mixture thoroughly to chill and dilute.

Strain the mixture into the pre-chilled Old Fashioned glass filled with fresh ice, preferably a large cube or chunk.

Express the orange zest over the cocktail to release its oils and place it in the glass as a garnish.
