The Makalapa is a tropical cocktail created by Lynnette Marrero at Llama Inn in New York City. Named for a crater-lake neighborhood in Honolulu, it mixes spiced rum, grapefruit, lime, and hibiscus honey syrup, then tops it with sparkling soda for a refreshing finish.
Add rum, hibiscus honey syrup, grapefruit juice, and lime juice to shaker.
Fill shaker with cubed ice.
Shake for 10-20 seconds.
Using a Hawthorne and fine mesh strainer, strain into a coupe glass.
Top with soda water.
