This is a fruity and herbal drink, and beautifully refreshing. Make the syrup ahead of time and store it in the fridge, and then you can make the orangeade up as you need it.
400g granulated sugar
About 4 good sprigs of rosemary
Fresh orange juice
1 Put the water, sugar and rosemary into a saucepan and heat gently, stirring, until the sugar has dissolved. Once all of the graininess has vanished, bring to the boil and then simmer for a few minutes. Remove from the heat and leave to cool, leaving the pieces of rosemary in the syrup to infuse. Pour into a jar and refrigerate until needed.
2 To make up the orangeade, combine one part cooled syrup with one part orange juice and one part fizzy water. Pour over ice cubes and garnish with a sprig of rosemary.
