In a blender put the cranberries,

Pour back the same orange juice, water and add sugar. I have brown sugar "Mistral Demerara".

Grind it all in a blender until smooth and strain through a sieve.

It is better to drain 2 times, then will not stay no unnecessary pieces.

For feed use long glasses or wine glasses. Pour the resulting syrup into glasses, then topped up with lemonade or sparkling water. The ratio of syrup and lemonade should be 50: 50. But you can request a number to adjust for themselves! Sugar can be used according to your taste, add it more if cranberries are very acidic.
