Simple Syrup (see recipe below)*
Juice of 6 freshly-squeezed lemons (approximately 1 cup juice)**
4 cups cold water***
1 sliced lemon, for garnish
Ice cubes

Basic Simple Syrup Recipe:

1 cup granulated sugar*
1 cup water

* You can reduce the sugar to 3/4 cup, if desired.

In a medium saucepan, combine sugar and water. Boil for 5 minutes, without stirring. Remove from heat and let cool before using.

Store in the refrigerator in an covered container. Sugar is a natural preservative, so Simple Syrup keeps for a while in the refrigerator. Eventually mold will begin to grow if stored too long
