Cut the lemons in half and juice them. Remove any of the seeds that have come out from the lemon. Keep the lemon skin for later, this is optional.
STEP 2
Add the lemon juice, water and sugar to a jug that can shut with a lid. Shake well until the water is a misty colour. Test to see if the taste is to your liking.
STEP 3
Add the ice and lemon skins (again the lemon skin is optional) to the drink and serve to your guests.
