Step 1

Use a blender or food processor to puree the strawberries. Strain them through a fine mesh sieve, if desired, to remove seeds. 

Step 2

In a small saucepan, over medium heat, stir together sugar and 2 cups water. 

Step 3

Bring to a boil, and stir until sugar is dissolved. Remove from heat and allow to cool to room temperature.

Step 4

Strain the lemon juice through a fine-mesh sieve into a 2-quart pitcher. Add simple syrup and pureed strawberries and stir to combine. Refrigerate until cold.

Step 5

When ready to serve, add 2 ½ cups of cold water and stir. Taste, and add more water if it's too sweet.

Step 6

Serve with ice.
