4 cups (600g) white sugar
3½ cups water
3 lemons
1 cup (250ml) freshly squeezed lemon juice
25g tartaric acid
1 litre soda water
Fresh mint leaves for garnish
Dissolve the sugar in the water in a non aluminium saucepan over gentle heat. Bring to the boil and boil for 5 minutes. Using a zester, remove all the zest from the lemons, avoiding any white pith. Add the zest and the lemon juice to the syrup and once it starts to boil, take off the heat and stir in the tartaric acid. Strain the syrup to discard the zest and leave to cool completely. Once cooled, pour into a 1 litre glass bottle and refrigerate. To make the lemonade, dilute 1 part syrup with 3 parts soda water.
Serve on ice with lots of mint and slices of lemon.
Makes: 1 litre cordial
Tip: You can refrigerate the bottled cordial for 1 month. Try the same recipe with limes and infuse your cordial with lemongrass and ginger.
