1 cup white, granulated sugar
1 cup water
1 cup lemon juice
2 to 3 cups cold water
Place the sugar and water in a small saucepan and bring to a simmer. Stir so that the sugar dissolves completely and remove from heat.
While the water is heating for the simple syrup, juice your lemons. Depending on the size of the lemons, 4 to 6 of them should be enough for one cup of juice.
Pour the juice and the simple syrup sugar water into a serving pitcher. Add 2 to 3 cups of cold water and taste. Add more water if you would like it to be more diluted . If the lemonade is a little sweet for your taste, add a little more straight lemon juice to it.
Refrigerate 30 to 40 minutes. Serve with ice, sliced lemons.
