The Poinsettia cocktail—just cranberry juice, orange liqueur, and champagne—has been showing up at every holiday brunch since the 80s, quietly surviving decades of cocktail snobs calling it too simple to be real mixology. Turns out those three ingredients are doing way more than you think: the champagne's acidity cuts sweetness, the Cointreau bridges cranberry's tartness with citrus warmth, and when you pour it right without murdering the bubbles, you get something that tastes elegant without needing a bartending degree. It's basically proof that the simplest cocktails are the hardest to get perfect, and maybe that's why your aunt's been making it the same way for thirty years.
