Place garlic and chilli in your Thermomix bowl and chop for 2-3 seconds on speed 8. Set aside.
To your unwashed Thermomix bowl, add fish sauce, vinegar, rapadura and water. Cook for 3 minutes, 100 degrees, speed 2. Set aside in a serving bowl or jug for a good 10 minutes to cool slightly.
Once cooled, add your pre-chopped garlic and chilli to the sauce along with the juice from 1 lime. Give it a stir, and serve!
