A dash of bitter Campari tames the perfumed notes of rose in this floral cocktail.
In a cocktail shaker combine vodka, sour mix, rose syrup, Campari and ice; shake until chilled about 30 seconds. Double-strain into an ice-filled Collins glass. Top with seltzer. Float a thinly sliced lemon wheel sprinkled with a little coarse sugar on top.
Combine equal parts lemon juice, lime juice and simple syrup.
