Combine the hulled and sliced strawberries and the fresh basil in a food processor and pulse a few times until they are smoothed. Set aside.

Add 1 cup of water to a small saucepan with the granulated sugar and turn on low-to-medium heat until the sugar has completely dissolved.

In a large pitcher, add in the lemon juice, strawberry and basil mixture, and the sugar water with 4 cups of cold, filtered water. Mix together.

Allow the lemonade to cool in the refrigerator. Serve with ice.
