Rinse your fresh blueberries thoroughly under cold water. Remove any stems or debris. Pat them dry with a clean kitchen towel.

Wash the basil leaves gently. Shake off excess water. Remove any thick stems, keeping only the tender leaves.

Add blueberries, basil leaves, honey, lemon juice, water, yogurt, salt, and lemon zest to your blender. Secure the lid firmly.

Blend on high speed for about 60 seconds until completely smooth. Stop and scrape down the sides if needed, then blend again.

Taste your Blueberry Basil Soup and adjust sweetness or tartness according to your preference.

For an extra-smooth texture, strain the soup through a fine-mesh sieve (optional).

Transfer the Blueberry Basil Soup to a covered container and refrigerate for at least 2 hours.

Before serving, give the soup a good stir, ladle into chilled bowls, and garnish as desired.
