Place all ingredients into the Thermomix bowl and cook 12 min/Varoma/speed 2/spatter guard.
Or to speed things up a notch, if you are really in a hurry for that dessert....throw it all in a saucepan, whack it onto the induction and stir to combine. Cook around 2-3 min/Induction 5 until bubbling and thickened.
Taste the sauce and decide if you need more fish sauce or even a pinch of salt. This will be dependent on the fish sauce you use.
