In a medium saucepan over medium heat, combine 1 cup of granulated sugar with 1 cup of water. Stir continuously until the sugar completely dissolves, about 3-5 minutes. Remove from heat and let cool.

Hull 1 quart of fresh strawberries and place them into a blender. Add 1 cup of water. Blend on high for about 30 seconds until smooth. Strain through a fine mesh sieve if desired.

In a large pitcher, combine the strawberry puree with the cooled simple syrup and 1 cup of freshly squeezed lime juice. Stir well.

Add the remaining 4 cups of cold water to the pitcher. Stir until everything is evenly incorporated. Adjust sweetness or tartness if necessary.

Cover the pitcher and refrigerate for at least 1 hour to allow flavors to develop.

Once chilled, fill tall glasses with ice and pour the strawberry limeade over it. Garnish with lime slices or fresh strawberries if desired.
