Prepare the Strawberry Purée:
In a blender, combine the strawberries and 1 cup of water. Blend until smooth.
Strain the purée through a fine mesh strainer to remove seeds, if desired.
Juice the Lemons:
Use a citrus juicer to extract 1 cup of fresh lemon juice from the lemons.
Mix the Lemonade Base:
In a large pitcher, combine the strained strawberry purée, lemon juice, and sugar. Stir until the sugar dissolves completely.
Add Water:
Pour in the remaining 3 cups of cold water and stir well. Adjust sweetness by adding more sugar or water, if necessary.
Serve:
Fill glasses with ice cubes (optional) and pour in the strawberry lemonade.
Garnish with fresh strawberry slices and lemon wedges for a festive touch.
