To make strawberry syrup wash and hull your strawberries. Cut strawberries into quarters. Place strawberries into a pot and add 32 ounces of water. Bring to a boil, then simmer for 15 minutes. Strain liquid, discard the strawberries. Add sugar, and cook for 5 additional minutes. Skim off any impurities on the top of the syrup. Pour into a container, and allow to cool. Store the syrup in the refrigerator for up to two weeks.
To make the Strawberry Limeade, fill a glass with ice, add 1/4 cup strawberry syrup, 1 cup of Sprite, and stir well. Add lime wedges, and garnish with a strawberry if desired.
