Instructions
Right now in Shanghai the fruit market are all carrying these terribly sour tangerines, they get sweeter as the season goes on but right now ...
In a blender mix the orange juice and sugar.
Taste a spoonful to see if sweet enough.
Adjust as needed
Add the ice and blend until smooth
Serve.
When it’s really hot out you can add a pinch of salt to the mix if you like, very Thai.
