I stopped drinking Diet Coke. It was a pretty brutal detox. I miss fizzy drinks though and full sugar drinks are just way too sweet. This is my compromise at the moment.
150gr fresh cranberries
40gr caster sugar
1, Put the cranberries in a small saucepan with the water and simmer, very gently until the cranberries are soft.
2, Transfer into a blender and blitz until smooth.
3, Pass this through a sieve to get rid of the skins and seeds and transfer back into a clean saucepan. Add in the sugar and heat gently until the sugar has dissolved.
4, Remove from the heat and leave to cool completely before mixing with soda water. Serve with ice.
