Place a whole hibiscus flower in the bottom of a champagne flute.
Fill glass with prosecco to 3/4″ of the rim.
Pour two teaspoons of the hibiscus syrup used to pack the flowers gently down the side of the glass. It will settle and layer in the glass creating the lovely ombré effect!
Notes
Consider refrigerating your hibiscus flowers so they will be chilled in your cocktails.
