Combine 3/4 c granulated sugar and 1/2 c water, boil until dissolved, to form a simple syrup.

Combine lemon juice and remaining cold water in a pitcher; mix.  Add simple syrup to taste.

Smash strawberries on a shallow dish, using a potato masher or a fork. Add the smashed strawberries to the lemonade mixture. Add remaining strawberries.
