Cranberry Lemonade

3 cups freshly squeezed lemon juice ( from about 20 lemons)

2 cups superfine sugar

3 cups water

1 1/2 cups cranberry juice

2 lemons, thinly sliced

1 Lime, thinly sliced

1 cup fresh cranberries, optional

Strain the lemon juice and combine it with the sugar in a large serving container.     (I like wide-mouthed jars.)  Stir until sugar is dissolved.  Add the water and cranberry juice and stir again.  Add a couple of trays of ice to chill the lemonade well.  Then add the lemon and lime slices, and the cranberries, if you care to, and serve.
