Prepare the Peaches: Wash and chop about four ripe medium peaches, ensuring to remove the pits while leaving the skin intact for added flavor.

Cook the Peach Mixture: In a medium saucepan, combine the chopped peaches with 2 cups of cold water and ½ cup of sugar. Heat over medium heat until boiling, then simmer for 5 to 7 minutes.

Cool and Refrigerate: Allow the peach mixture to cool to room temperature for about 10 minutes, then refrigerate until fully chilled—about 30 minutes.

Strain the Mixture: Use a fine mesh sieve over a large bowl to strain the peach mixture, pressing down to extract as much liquid as possible while discarding the solids.

Mix in Water and Lemon Juice: Pour the strained peach liquid back into the saucepan, and stir in 2 cups of cold water and 1 cup of lemon juice. Mix well and adjust sweetness if needed.

Serve: Fill glasses with ice, pour the lemonade over it, and garnish with mint leaves and peach slices.
