A delightful sparkling cocktail with a tangy cranberry twist.
In a medium saucepan, combine the cranberry juice and sugar. Bring to a boil over medium heat, then reduce to a simmer.
Stir occasionally to prevent the sugar from sticking to the bottom of the pan.
Simmer the mixture until reduced by two-thirds, then remove from heat and let it cool for 30 minutes.
Allowing the reduction to cool ensures it mixes well with the other ingredients.
In a small jug, combine the cooled cranberry reduction, Cointreau, and lime juice.
Mix thoroughly to ensure the flavors are evenly distributed.
Place a sugar cube in each serving glass. Pour the cocktail base evenly over the sugar cubes.
The sugar cube adds a touch of sweetness and a fun fizz when the sparkling wine is added.
Top each glass with chilled sparkling wine and serve immediately.
Serve immediately to enjoy the full effervescence of the sparkling wine.
