Prepare the Glass: Rub the rim of a champagne flute with a lemon wedge. Dip the rim into sugar on a plate, rotating until it's evenly coated.
Mix the Base: Fill a cocktail shaker with ice. Add the vodka, blue curaçao, and lemon juice. Shake vigorously until the mixture is well chilled.
Assemble the Cocktail: Strain the mixture into the prepared champagne flute. Top off the glass with champagne, allowing the bubbles to mix gently with the base.
Garnish: Drop a maraschino cherry into the glass for a pop of color.
Serve: Serve immediately and enjoy this stunning creation!
