Ingredients

4 ripe peaches, pitted and sliced 

1/4 cup sugar 

2 teaspoons fresh lemon juice 

4 bottles (750 mL each) Prosecco or Champagne 

1/4 cup elderflower liqueur, preferably St-Germain 

Preparation

Puree peaches, sugar, and lemon juice in a blender until smooth. Pass mixture through a fine sieve into a metal bowl. Freeze until firm, at least 6 hours.

Scrape granita with a fork until fluffy. Freeze until ready to use.

Fill 20 Champagne flutes halfway with Prosecco (you’ll have some left over). Add 1 tablespoon liqueur to each. Top each glass with 1 tablespoon granita. Serve immediately.
