Vanilla Old Fashioned

Select and pre-chill an Old Fashioned glass.

Prepare an orange zest twist for garnish.

Stir the bourbon whiskey, Giffard Vanille de Madagascar, and Bob's Vanilla bitters with ice.

Strain the mixture into the ice-filled Old Fashioned glass, preferably over a large cube or chunk of block ice.

Express the orange zest twist over the cocktail, then use it as a garnish.
