This recipe is from my Dad's files and it has become my favorite cocktail of late. Delicious and refreshing. You could use sparkling wine if you can't get champagne. For a fancy sugared rim, rub the rims of the glasses with a slice of lemon and then dip into sugar. Cheers!
8 tablespoons Limoncello
4 teaspoons lemon juice
1 bottle brut champagne
Roll up the lemon peel strips and place each in a champagne flute. Add 1 tablespoon Limoncello and ½ tsp lemon juice to each glass. Divide the champagne evenly among the glasses and serve.
