The most DELICIOUS LEMONADE you can make

Ingredients for 2 litres
2 large untreated lemons (or 4 smaller ones) both the zest and the juice (which should be around 200-250 ml)
2 liters of natural mineral water
70 g sugar
To flavor you can also use a few sprigs of fresh or dried mint or a few stems of fresh or dried lavender.
I particularly like to add 1 tablespoon of edible rose water to the total lemonade, when it is already cold
