Combine sugar, 1 cup of water and lemon zest in a small saucepan. Bring to a simmer and cook for 10 minutes. Cool.
Puree strawberries in a food processor until smooth. Strain the puree through a fine mesh strainer, pressing down on the solids to get all the good juice out.
Strain the cooled lemon sugar syrup through a fine mesh strainer.
Combine the syrup, the strawberry puree, the lemon juice and the remaining water in a large pitcher and stir. Add ice cubes and serve!
Notes
Lemons: Try and get lemons that have a little give to them so they are easy to juice. And if you have a stubborn hard lemon, pop it in the microwave for 15 to 20 seconds…this will magically soften it up!
Strawberries: Local in-season strawberries are the very best for this recipe, but you can also grab a carton at the supermarket. Want to mix things up? Use raspberries instead, or a mix of berries!
Sugar: We do find that the sugar is necessary to sweeten up the tart taste of the lemons. You can cut it back to half a cup if you want, and then stir in more once your lemonade is ready if you think it needs more.
