Went to a Vietnamese cafe for din dins the other night, and was encouraged to try the coconut shake. It was delicious but very sweet and my initial attempt at asking what was in it didn't go well (the answer was yes OK with lots of nodding) so I decided I had to try to make one at home. Still experimenting but its pretty damn good so far.

I use a good stick blender, my food processor can't do ice.

Handful of ice
1/4 of a tin of coconut milk
Same volume coconut water
Small handful of fresh pineapple
Squeeze of lime juice

Blend til smooth

You can take the fruit out and its still amazing. Perfect hangover cure too :-) especially if you add some vodka
