A really easy recipe, more suited for Spring or Summer drinking really but very refreshing served over ice cold sparkling water.
Makes 1.2 litres
3 large unwaxed lemons
350g / 12oz caster sugar
1 litre water
Wash the lemons, then thinly pare off the rind with a vegetable peeler, being careful not to pare off too much of the bitter pith. Put the rind in the cooking pot of a slow cooker with the sugar and water. Cover and switch the cooker to high.
Heat for 3o minutes, then stir until the sugar has dissolved. Cook for a further hour and a half, then leave to cool.
Halve the lemons and squeeze out the juice. Stir into the syrup, then strain through a sieve and pour into sterilized bottles. Store in the fridge for up to 10 days. Serve over ice and dilute to taste (4 parts water to 1 part cordial is about right) with still or sparkling water.
