Wash 4 ripe peaches under cool running water. Slice in half, remove the pit, and dice or blend into a puree.

Roll 4-5 fresh lemons on a countertop, then cut in half and squeeze to obtain 0.5 cup of lemon juice.

In a saucepan, combine 1 cup of water and 0.5 cup of sugar over medium heat and stir until dissolved.

In a large pitcher, mix peach puree, lemon juice, and the cooled sugar-water mixture. Add 3 cups of cold water and stir well.

Serve the Peach Lemonade over ice cubes in glasses.

Garnish each glass with mint leaves or lemon slices before serving.
