Lemonade

6 unwaxed lemons

Half a cup of sugar

Quarter of a cup of water

1.25 litres of chilled water, still or sparkling

Using a zester, grater or sharp knife, remove the zest from the lemons. If using a knife, make sure it is finely shredded. Place in a small saucepan with the sugar and water. Heat gently until all the sugar is dissolved and the mixture has just reached boiling point and then turn off the heat. Juice the lemons and then add the juice to the pan. Stir and then strain into a container to remove the zest. Refrigerate the mixture. When ready to drink, place the mixture in a large pitcher and then add the chilled water. Serve with ice and slices of lemon.
