Prepare the Blueberry Mixture:

In a blender, combine half of the blueberries with the limoncello. Blend until smooth. If you prefer a smoother texture, you can strain the mixture to remove the blueberry skins.

Assemble the Drinks:

In each glass, place a few fresh blueberries and, if desired, a couple of ice cubes.

Pour about 2 tablespoons of the blueberry limoncello mixture over the blueberries.

Add the Prosecco:

Carefully fill the glass with Prosecco, allowing it to mix gently with the limoncello mixture. The Prosecco will fizz up, so pour slowly.

Garnish and Serve:

Garnish each glass with a sprig of mint and a slice of lemon on the rim.

Serve immediately and enjoy the refreshing taste.
