This lemonade from The City Bakery is distinctively tart. You can make it lighter or sweeter by adding more water or sugar to taste.
In a pitcher or container, whisk together the sugar and water until the sugar dissolves. Add lemon juice and stir. Puree the strawberries and strain to remove the seeds. Add the strawberry puree to the lemon mixture and stir. To serve, pour into 10-ounce glasses filled with ice.
