Start by making your homemade lemonade or using store-bought for quicker preparation. Juice 6-8 lemons into a measuring cup. Combine the lemon juice with 1 ½ cups of sugar and 8 cups of water in a large pitcher, stirring until the sugar dissolves.

Wash 4-5 ripe peaches thoroughly, then slice them in half, removing the pit, and reserve a quarter of the slices for garnish. Chop the remaining peaches into smaller chunks.

In a blender, combine the chopped peach chunks with 1 cup of the chilled lemonade and 1 tablespoon of fresh mint. Blend until the mixture is completely smooth.

If you prefer a thinner consistency, strain the blended peach mixture through a fine mesh strainer, then pour into the pitcher.

Add the remaining lemonade and 8 cups of water to the strained peach mixture, stirring until well combined. Adjust sweetness as desired.

Serve the peach lemonade chilled over ice cubes, garnished with mint and peach slices.
