Combine 8 cups of water with 4 cups of lemonade in a pitcher. If using homemade lemonade, mix lemon juice with sugar until dissolved and chill for 30 minutes.

Wash and slice 4-5 ripe peaches, removing pits. Optionally peel peaches for enhanced flavor.

Blend sliced peaches with 1 cup of chilled lemonade base and 1 tablespoon of mint until smooth, about 30-45 seconds.

Optional: Strain the blended mixture through a fine sieve into a bowl for a smoother texture.

Combine the strained or unstrained peach mixture back into the pitcher, stirring gently until well mixed.

Serve in tall glasses over ice, garnished with peach slices and mint leaves.
