1 1/4 cups Cointreau or Grand Marnier 1 1/4 cups cranberry juice cocktail 1/2 cup plus 2 tablespoons fresh lime juice 3 tablespoons superfine granulated sugar 4 cups chilled Champagne or other sparkling wine
Stir together Cointreau, juices, and sugar and chill, covered, 2 to 6 hours. Just before serving, divide among 10 Champagne flutes and top off with Champagne.
garnish the drinks with skewers of sugar-coated fresh cranberries (thawed frozen ones will work just fine, too).
