Rinse off lemons and cut in thin slices.

Place lemons, salt and sugar in a medium saucepan and mash lemons with a potato masher or spoon.

Mash until the sugar is dissolved.

Juice will thicken to a thin syrup consistency.

The juicing should take about 3-5 minutes.

Using a strainer pour the liquid into a large measuring glass or pitcher. Squeeze the lemons again to catch any leftover juice. Stir in water and chill for one hour or drink soon afterward.
