1 cup superfine sugar
1 1/2 cups freshly squeezed lemon juice, from 10 to 12 lemons
Fresh mint leaves, for garnish
Sliced lemons, for garnish
Optional flavorings: basil, scraped vanilla beans, freshly grated ginger (see Cook's Note)
For a twist on classic lemonade, try infusing the sugar syrup with fresh basil, a scraped vanilla bean or freshly grated ginger root. Add it to the syrup while it cools. Strain out any solids before using.
