Scrub all Lemon (5) clean, then pat dry with a dry towel or tissues. Use a hand grater or lemon grater to zest the lemons.
Combine Granulated Sugar (3/4 cup), Water (1 cup), and lemon zest in a small pot to make simple syrup. Heat the pot over medium-high heat until mixture starts to simmer and stir until sugar dissolves.
While the simple syrup cools, juice the lemon and strain to remove all the seeds and the pulp.
Combine the freshly squeezed lemon juice and simple syrup in a pitcher. Add Water (2 cup) to dilute. If you prefer your lemonade even thinner, add up to one cup more or until to your liking.
Refrigerate for 2-3 hours, then serve over with Ice (to taste) and slices of lemon if you like things pretty. Enjoy!
