Lime Syrup

• 200 g Castor sugar
• 300 ml Water
• Juice of 3

Mix the sugar, water, lime juice and zest together in a heavy-based saucepan. Stir over a medium heat until the sugar has dissolved. Bring to the boil, reduce the heat and continue to cook for 3 minutes. Skim off any scum that rises to the surface. Transfer the syrup to a clean bowl and allow to cool. Allow the lime zest to infuse and flavour the syrup. Store in a sealed container in the fridge
