Ingredients
2 cups white grape juice, divided
3 packets unflavored gelatin
2 1/2 cups Champagne (or sparkling wine like Prosecco or Cava), plus more for pouring
1/2 cup St-Germain liqueur
Pomegranate seeds
Preparation
Bring 1 cup grape juice to a boil. Whisk in gelatin until dissolved. Pour the mixture into a 9-by-13-inch baking dish. Stir in 1 more cup of grape juice, 2 1/2 cups of Champagne or sparkling wine, and St-Germain liqueur. Let chill until the gelatin is set, 2 to 3 hours. Cut the gelatin into cubes and distribute it among glasses, also dropping pomegranate seeds in each. When ready to serve, pour more Champagne over the gelee (serve with small spoons).
