Begin by pouring some red sanding sugar into a small dish, allowing easy access for rimming. In another container, pour a bit of pineapple juice for dipping. Take your Champagne flute, dip the rim into the pineapple juice, then quickly roll it in the red sugar until fully coated, creating a festive and sweet barrier.

Carefully pour 2 ounces of pineapple juice into the sugar-rimmed glass, allowing the vibrant color to shine through. Following this, add 1 bar spoon of Blue Curaçao, taking care to pour gently to avoid a color splash. Stir the mixture softly with a bar spoon, ensuring that the ingredients blend well while maintaining the beautiful green hue.

Now, it’s time to introduce the bubbly magic! Slowly top off your mixture with 3 to 4 ounces of chilled Prosecco, allowing the effervescence to rise and create a lively display. Observe as the bubbles dance beautifully with the colored juices, enhancing the festive appearance of your Grinch Mimosa.

Once you have topped the drink, serve it right away to enjoy the full effect of the fizz and freshness. Consider placing the finished glass on a decorative coaster to showcase its vibrant colors. This Grinch Mimosa is now ready to be enjoyed, bringing a cheerful spirit to your holiday gathering!
