Begin by rinsing 1 pound of fresh strawberries under cool water, remove the green stems, and slice the strawberries in half. Blend on high for about 30 seconds until smooth.

In the same blender, combine the strawberry puree with 2 cups of filtered water, 1¼ cups of freshly squeezed lemon juice, and 1 cup of simple syrup. Blend for 15-20 seconds until well combined.

Strain the mixture through a fine-mesh sieve into a large bowl, pressing the puree with a spatula to extract as much liquid as possible, discarding the pulp.

Pour the strained strawberry lemonade concentrate into a large pitcher and add 3 cups of chilled club soda. Stir gently for about 10 seconds to mix without losing carbonation.

Fill glasses with ice cubes, pour the Strawberry Lemonade over ice, and garnish with a slice of lemon or fresh mint leaves. Serve immediately.
