Wash, pit, and dice the ripe peaches. In a medium saucepan, combine with sugar, water, and fresh lemon juice. Simmer for 10-15 minutes until peaches are soft.

Mash the mixture to create a chunky puree. Strain through a fine sieve into a bowl and allow to cool to room temperature.

In a small saucepan, combine equal parts sugar and water over medium heat, stirring until sugar fully dissolves and cool completely.

Juice the fresh lemons to get approximately one cup of lemon juice. Strain to remove pulp and seeds, then mix with cooled simple syrup in a large pitcher.

Add peach puree to the lemonade base and gradually mix in cold water, adjusting sweetness and tanginess to taste.

Chill the assembled lemonade in the fridge for at least 30 minutes. Serve over ice with garnishes.
