Mix the cognac and curacao several hours ahead of time.
When ready to serve, pour the necessary amount of this mixture over a block of ice or ice mold in a *cold* punch bowl, and add *thoroughly chilled* champagne.
Stir and serve at once, WITHOUT LADLING BACK AND FORTH OVER THE ICE, as this will eliminate the bubbles.
