Raspberry lemonade

Put 150g caster sugar and 1 cup water into a pot. Bring to a simmer, remove from the heat and pour into a blender. Add the juice of 4 lemons and 200g fresh raspberries and blend until smooth. Strain if you don’t like it pulpy. Pour into a pitcher and add ice. Add 600-800ml sparkling water or to taste – ideal as a summertime afternoon refresher.
