Prep Glass: Fill a Coupe glass with ice. Give it a quick stir to chill it and set it aside.
Add Sugar: Pour 1 bar spoon of rich sugar syrup into the shaker.
Add Orange Juice: Add ¼ oz fresh orange juice.
Add Dry Vermouth: Measure and pour ¾ oz Dry Vermouth into the shaker as well.
Add Rum: Finally, add 1¾ oz Dark Rum to the mix.
Shake Well: Fill the shaker with ice, close it and give it a good shake (10-15 seconds).
Strain: Take the Coupe glass and discard the ice inside. Then, using the cocktail strainer and the fine strainer, strain the shaken drink into the chilled glass.
Garnish: Garnish with an orange zest twist (express the orange zest on top of the drink and then place it on the rim of the glass or drop it directly inside) and serve immediately.
