Salted Caramel Espresso Martini

Select and pre-chill a martini glass.

Prepare a garnish by twisting an orange zest and setting aside a caramel candy.

Shake the vodka, espresso coffee, salted caramel syrup, vanilla bitters, and saline solution with ice until well chilled.

Strain the mixture into the prepared martini glass.

Express the orange zest twist over the cocktail to release its oils, then discard the twist.

Garnish the drink with the salted caramel candy attached to the rim.
