Add tangerine juice, sugar and ginger to a medium saucepan. Bring to a boil over medium heat, stirring to dissolve the sugar. Let boil for about two minutes.
Remove pan from heat and let cool. Refrigerate for a few hours or preferably overnight so the flavors may blend.
Before serving strain the syrup to remove the ginger and pour into a serving container.
Add 2 to 3 teaspoons of syrup to a Champagne flute and top with prosecco or sparkling wine.
Syrup keeps for a few weeks in the refrigerator.
Notes
* This makes enough syrup for about 32 drinks – which translates to 4 bottles of sparkling wine. * Look for freshly squeezed tangerine juice at your grocery store to make this drink even simpler to make. * Syrup will keep frozen for a few months.
