1 lime - cut into 6 chunks
1 oz rose syrup
4 oz Bacardi raspberry-flavored rum
In a cocktail shaker, muddle the lime with rose petals and rose syrup. Add rum and about 1/2 cup of ice. Shake well. Pour into a highball glass and add ice. Top with champagne and rose petals for garnish.
My highball glasses are from Anthropologie.
