Ingredients:
- 2 cups water
- 1 cup granulated sugar
- 0.5 cup dried hibiscus flowers
- 1 cup fresh raspberries, lightly crushed
- 1 tbsp lemon juice
- 1.5 liters chilled Prosecco
- 1 cup sparkling water
- 1 pint frozen raspberries
- 1 bunch fresh mint leaves
Instructions:
- Combine the 2 cups water, 1 cup sugar, and 0.5 cup hibiscus flowers in your saucepan. Heat over medium until the sugar completely dissolves and the liquid turns a deep, dark red. Note: Don't let it reach a rolling boil, or the hibiscus can become bitter.
- Toss in the 1 cup crushed raspberries and the 1 tbsp lemon juice. Simmer gently for 10 minutes until the berries look pale and the liquid is syrupy.
- Pour the mixture through a fine mesh strainer into a glass jar. Press down on the solids with a spoon until you've squeezed out every drop of flavor.
- Place the syrup in the fridge for at least 2 hours. It needs to be stone cold to the touch before it meets the bubbles.
- Drop 3-4 frozen raspberries into each glass. This keeps the drink cold without diluting the flavor like regular ice would.
- Measure about 2 tablespoons of the chilled hibiscus syrup into the bottom of each glass. It should sit heavy and dark at the bottom.
- Slowly pour the chilled Prosecco over the syrup. Watch for the shatter of bubbles against the glass as the colors begin to swirl.
- Add a splash of the 1 cup sparkling water to each glass. This creates a lighter, more refreshing finish.
- Gently tuck a sprig of fresh mint into the top of the glass. You want the guest to smell the mint with every sip.
- Serve immediately while the carbonation is at its peak. The drink should look vibrant, bubbly, and perfectly ombre.
