2 cups sugar
1 cup water
1 (16-ounce) bag frozen peaches, thawed
1 teaspoon grated orange peel
1 (16-ounce) bag frozen strawberries, thawed
1 (16-ounce) bag frozen blueberries or blackberries, thawed
4 to 6 (750-ml) bottles Prosecco or other sparkling wine, chilled
Fresh strawberries, raspberries, and blueberries, for garnish
Orange peel twists, for garnish
Stir the sugar and water in a large saucepan over medium heat until the sugar dissolves, about 5 minutes. Cool completely.
Puree the peaches and orange peel in a blender with 1/2 cup of the sugar syrup until smooth. Strain through a fine-meshed strainer and into a bowl. Cover and refrigerate. In a clean blender puree the strawberries with 1/3 cup of the sugar syrup until smooth. Strain through a clean fine-meshed strainer and into another bowl. Discard the seeds. Puree the blueberries in a clean blender with 1/3 cup of the sugar syrup until smooth. Strain through a clean fine-meshed strainer and into a third bowl. Discard the seeds and solids. Pour each of the purees into clear glass bowls or small pitchers.
For each serving, pour 2 to 4 tablespoons of the desired fruit puree into a Champagne flute. Slowly pour enough Prosecco into the flute to fill. Gently stir to blend. **NOTE: After trial and error, my friend Holly and I finally figured out if you put the sparkling wine in a large pitcher, and then add the puree, you can control the spillover better -- it poured easily out of the pitcher into the glasses without spilling over. Garnish with the whole berries, as desired, and serve.
Do-Ahead Tip: The fruit purees can each be made 1 day ahead. Cover separately and refrigerate.
I did Mango in place of the peach and dropped in 2 mandarin orange sections in each glass. I used a cheap sparkling wine Andre Spumante and we didn't feel it lacked any flavor.
