Don't use your best Champagne for this dessert—any affordable bottle of cava or Prosecco will do. The key ingredient in this machine-free sorbet is the apricots: Choose the ripest, most fragrant ones you can find.
Ingredients
1 cup sugar
1 pound apricots plus more for serving, pitted, sliced
3/4 cup sparkling wine plus more for serving
Directions
Bring sugar, 1 pound apricots, 3/4 cup sparkling wine, and 2 cups water to a boil in a medium saucepan. Reduce heat and simmer, stirring occasionally, until apricots are very tender, 10-15 minutes. Let cool completely.
Transfer apricot mixture to a blender and purée until smooth. Add water to apricot mixture so it measures 4 cups. Transfer mixture to a large shallow baking dish. Freeze until solid, at least 4 hours.
To serve, scoop sorbet into coupe glasses or bowls and top with more apricot slices and some sparkling wine.
