Cranberries are cultivated in Canada, and tradition there calls for hosts to make a punch for Christmas guests. Here, the crop and the custom merge in a delightful champagne cocktail, which takes a French turn with the addition of crème de cassis.
Preparation Place 2 tablespoons cranberry juice and 1 tablespoon crème de cassis in each of 12 champagne flutes. Pour 1/4 cup champagne into each and serve.
