Begin by selecting two ripe peaches, ensuring they are soft to the touch for optimal sweetness. Peel the peaches and slice them into manageable pieces.

In a blender, add the sliced peaches and blend on high speed until completely smooth, about 30 seconds. Strain the puree if desired.

In a pitcher, combine the peach puree, lemon juice, and honey. Stir until the honey is dissolved and well-mixed.

Fill glasses halfway with the peach mixture. Gently pour in the chilled sparkling water and stir lightly.

Garnish with fresh mint leaves just before serving.
