Refreshing Lemonade

In this heat, everyone wants to feel refreshed, so why not quench your thirst with homemade lemonade? It's simple, needs very few ingredients and will take you less than 5 minutes to prepare.
Here's what you'll need:

1 cup lemon juice (5 to 6 squeezed lemons)
slices of 1 lemon for decoration
1/2 to 3/4 cup white sugar
1 cup ice cubes
4 cups cold water
1/2 cup fresh mint (optional)
1 beautiful decanter
In the decanter, add the lemon juice, the sugar and stir to help dissolve the sugar as much as possible, then add the ice and top it off with the water. The lemon and mint can be added at the bottom of each glass for flavor or on top of each glass for decoration.
Enjoy!
