Monte Whiskey Sour

Use 2:1 rich simple syrup for its listed portion.

Chill an Old Fashioned glass in advance to ensure it's ready for serving.

Prepare an orange zest twist for garnishing.

Combine bourbon whiskey, Amaro Montenegro, freshly squeezed lemon juice, rich sugar syrup, and egg white or cocktail foamer in a shaker.

Add ice to the shaker and shake vigorously.

Strain the mixture back into the shaker, discarding the ice.

Shake again without ice to create a frothy texture.

Fine strain the cocktail into the pre-chilled Old Fashioned glass.

Express the orange zest twist over the cocktail to release its oils, then use it as a garnish.
