In a pitcher combine the lemon juice, simple syrup and water. You can add ice to the pitcher, or I prefer to serve the lemonade in glasses over ice so the lemonade doesn’t get diluted.
Garnish with the mint leaves and lemon slices, if desired.
Notes
You can double or triple this recipe as needed/desired, and know that you can dial up and down the sweetness or the tartness as you and your people like. We like ours on the slightly tart side. But the good news is that once you have a batch of simple syrup made and ready to go (simple syrup is just sugar dissolved in hot water and then chilled), people can add a bit more sweetness to their individual glasses. Everyone gets the lemonade of their wishes.
