Wash and chop 4 ripe peaches into small chunks, discarding the pits. Place the chopped peaches into a mixing bowl.

In a medium saucepan, combine chopped peaches, 2 cups of water, and ½ cup of sugar. Bring to a gentle boil, then reduce heat and simmer for 5-7 minutes until peaches are soft.

Remove the saucepan from heat and let the peach mixture cool for about 10 minutes. Transfer to the refrigerator to chill completely for 20-30 minutes.

Set a fine mesh sieve over a large bowl and pour the peach mixture through, pushing down with a spoon to extract as much juice as possible.

In a large pitcher, mix the strained peach juice with 2 cups of cold water and 1 cup of lemon juice. Stir thoroughly and taste for sweetness.

Fill glasses with ice and pour the lemonade over each glass. Garnish with fresh mint leaves and slices of peach.
