2 cups of hot water
1 cup of sugar
1 or more cups of lemon juice or 6 large lemons, squeezed or 8 small lemons, squeezed
4-6 cups cold water and ice cubes
Squeeze your lemons. Then put two cups of hot water into a jug and dissolve the cup of sugar in it. This only takes a minute of stirring. Then pour your lemon juice in (I generally strain it to remove pulp) and stir that in. After that, I usually add a bunch of ice cubes and enough water to fill the jug. Of course, it'll be more concentrated until the ice melts and doesn't taste as good warmish as it does cold.
And as you can see, I don't use exact science for this recipe. That means that every time is a little different. And you can see just how to make it the way that you like it the best.
It'll taste different because this is real. … But trust me, you will not be disappointed.
