Prepare the pie crust as directed. Cool completely. Leave oven on 190°C.
To make the filling, place the coconut milk and sugar into the Thermomix bowl and cook 45 min/Varoma/speed 4 until caramelised and sticky.
Add remaining filling ingredients to the Thermomix bowl and blend 10 sec/speed 8.
Place the baked pie shell onto a tray in the oven and pour the filling mixture into the shell. Push into the oven and bake until just set in the centre, about 40-45 minutes depending on the accuracy of your oven temp.
Transfer to a cooling rack and allow to cool completely.
Before serving, toast the flaked coconut in a hot oven for just a few minutes until well coloured. Remove and set aside.
Place the cream and sugar into the Thermomix bowl and whip 10-20 sec/Butterfly/speed 4 or until soft peaks form. Stir through the finely grated lime zest using your spatula.
Top the pie in the centre with the cream and garnish with the toasted coconut.
