How to Make It
To prepare sugar syrup, combine water and sugar in a small saucepan. Bring to a boil; cook 2 minutes or until sugar dissolves. Add ginger. Remove from heat; cool. Chill 4 hours.
Strain sugar syrup through a colander into a bowl; discard ginger. Place 1/3 cup sugar syrup in a blender; reserve remaining syrup for another use. Add rind, juice, and apricots to blender; process until smooth. Spoon 2 tablespoons apricot puree into each of 8 glasses. Top each with 1/3 cup prosecco; stir gently.
