Pour 1 ounce of limoncello and ½ ounce of blueberry lavender syrup into the glass.

Gently pour 3 ounces of Prosecco over the infused limoncello and syrup mixture.

Top off the drink with 1 ounce of club soda for a refreshing effervescence.

Give the cocktail a gentle stir to ensure all the flavors are harmoniously blended.

Garnish the glass with a few fresh blueberries and a sprig of lavender.
