I start by pouring a little corn syrup onto a small plate and swirling the rim of each champagne flute through it. Then I dip the sticky rim straight into festive sugar crystals for that sparkly, holiday-party look. This small touch takes seconds but makes the whole drink feel special.
Next, I drop a small handful of frozen cranberries into the bottom of each prepared glass. I squeeze a wedge of fresh lime right over the cranberries before they go in, which wakes up their flavor. The frozen fruit also chills the drink naturally as it sits.
I fill each flute about one-third of the way with chilled cranberry juice cocktail. If I'm making a mimosa with cranberry and orange juice, this is the point where I add a small splash of orange juice too, right on top of the cranberry layer.
Slowly, I top off each glass with cold champagne or prosecco, pouring gently along the side of the glass so the bubbles don't overflow. Watching the layers swirl together is honestly my favorite part of making this recipe.
Finally, I finish each glass with a sprig of fresh rosemary and a few extra cranberries floating on top. I serve these immediately while they're still fizzy and ice-cold, because that bubbly texture is really what makes this drink so fun to sip.
