Then add the juice from the lemons to the liquid. It makes about a cup total. Stir well, and let sit for several hours. Meanwhile, prepare the glasses by putting them into the freezer. To serve, poor concentrate into a chilled glass and add cold water and ice.
Early testing suggests one part concentrate and two parts water.
If you like a sweet drink, add more sugar to the glass. Page content copyright 1998 by John M. Dlugosz.
