Jacktini

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

Chill a martini glass in advance to prepare for serving.

Prepare a lemon zest twist for garnishing.

Shake the Tennessee whiskey, mandarin liqueur, freshly squeezed lemon juice, and rich sugar syrup with ice until well-chilled.

Fine strain the mixture into the pre-chilled martini glass.

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