Champagne Cocktail, no. 3

Choose a large tapering champagne cocktail glass; inside of this build a tower of 4 ice cubes, crown it with a lump of sugar saturated with 4 dashes of orange bitters. Against the sides of the glass lean 2 sticks of ripe fresh pineapple, encircle the ice tower with a spiral of green lime peel, and fill with well chilled champagne, medium dry, and not too acid in type. Now as the crowning gesture carefully float on 1 tbsp of Cointreau.
