Start by washing the artichokes well. We remove the superficial leaves, until we reach the most tender part. These we discard them. When we reach the tender leaves, we continue separating them from the heart, but we put them in a large jar.
When we get to the heart, we cut it into small pieces and add it to the jar.If you want to add lemon, squeeze half a lemon into the jar over the artichokes. Fill with a liter of water and let stand in the refrigerator until the next day.
Serve, previously straining the drink, with a few ice cubes and some mint leaves.
