1 oz Rum, Plantation Grand Reserve 5 year
1⁄2 oz Lime juice
1⁄2 oz Pineapple juice
1⁄2 oz Cane syrup
1 oz Rum, Plantation Grand Reserve 5 year (as float)
Shake first 6 ingredients. Strain over rocks. Garnish with remaining 1 oz rum.
This works better as a rocks drink (especially given the float), so I've modified the original recipe in that regard.
