1.5oz Aged Rum
.75oz Lime Juice
1oz Simple Syrup
2 Dashes Angostura Bitters
6-8 Mint Leaves
2oz Dry Sparkling Wine
In a shaker, combine all ingredients except the sparkling wine. Shake with ice. Double-strain into a chilled glass, top with sparkling wine and garnish with a single mint leaf.
Fantastic cocktail, but a bit on the sweet side, next time I would use a little less simple syrup.
