I modified this from another recipe I found, to make it a bit more glamorous... I filled the bottom of the glasses with rock candy, for sparkle and sweetness.
1 oz Grand Marnier, or other orange flavored liqueur
2 oz chilled Champagne
Handful of rock candy
Place rock candy in the bottom of a cocktail glass or small shooter. Add the orange liqueur, then top with cold champagne. Serve while fizzling! Enjoy!
