In a medium saucepan, combine 1 cup of sugar, 1 cup of water, 1 cup of sliced fresh strawberries, and 1 cup of fresh basil leaves. Heat over medium heat, stirring frequently until the sugar completely dissolves. Let it simmer gently for about 5 minutes.

Remove from heat and let the mixture cool slightly for about 5 minutes. Strain the syrup into a pitcher using a fine mesh sieve, pressing the solids to extract as much flavor as possible. Discard the solids.

Stir in 1 cup of freshly squeezed lemon juice and 2 cups of cold water or sparkling water to the strained syrup and mix well. Adjust the sweetness by adding more water or sugar to taste.

Refrigerate for at least 1 hour or serve immediately over ice for a refreshing drink.

Pour the chilled Strawberry Basil Lemonade over ice and garnish with a basil leaf and a lemon wheel before serving.
