Fill a glass with ice and add the lemon juice and passion fruit simple syrup. Top with sparkling water and garnish with a slice of lemon and a few passion fruit seeds.
FOR A PITCHER OF PASSION FRUIT LEMONADE:
Combine the lemon juice and simple syrup in a pitcher and refrigerate until very cold about 2 hours. Chill the unopened sparkling water at the same time. You want both components to be very cold before combining them.
Just before serving add the sparkling water to the lemon juice mixture and stir.
Fill the glasses with ice and add lemonade 3/4 of the way into a glass. Garnish with lemon slices or passion fruit seeds as desired.
