Here in the states we’d call this limeade. I made this tonight, and it was very good. I used sweetened condensed coconut milk (dairy allergy) and ended up doubling the amount because it was too tart for me with the amount given in the recipe. Your mileage may vary.
It does smell amazing.
Oh man! I used to love Orange Julius. I will have to try that next time. I bet mandarins would work still.
