Water 1 l
Lemon (you can lime) 1 pc.
Honey (instead of sugar) 2 tbsp
Ice (cubes)
Mint (leaves, optional) 1 bunch

Squeeze lemon juice into a pitcher of water (preferably by hand, using a tablespoon, so that a little pulp gets into the drink), add honey, mix well so that it dissolves.
At the end, add mint leaves (optional) and ice cubes, stir again and “mash” the mint in lemonade a little.
