• ½ ounce fresh-squeezed lime juice
• 1 ounce fresh-squeezed grapefruit juice
• ½ ounce honey cinnamon syrup
• ½ ounce Chartreuse
• 2 ounces Haleakala Distillers Maui Okolehao (from Hawaii) or 1 ounce Cotton & Reed Dry Spiced Rum and 1 ounce of Cotton & Reed White Rum (from DC)
• Pebble or semi-crushed ice
• 2–3 dashes of Angostura bitters

Add the lime and grapefruit juices to a glass, then add the honey cinnamon syrup, Chartreuse and your pick of either Okolehao or a 1:1 ounce mix of Cotton & Reed white and dry spiced rum. Add ice until the drink is topped off. Use a stir stick to lightly mix. Finish with 2 to 3 dashes of Angostura bitters.

To make the honey cinnamon syrup:

• 1 cup water
• 1 cup sugar
• 5 cinnamon sticks
• 1 spoonful raw honey (Rosner uses Really Raw Honey from Baltimore)

Stir all ingredients in a small saucepan. Bring the ingredients to a boil, then simmer for about 20 minutes, or until the mix reduces to a syrup-like consistency. Let the syrup cool, then cover and store in a refrigerator.
