Place garlic, chillies, ginger, lime leaves, shallots and EVOO into Thermomix bowl and chop 4 sec/speed 6.
Saute 5 min/Varoma/speed 2/spatter guard.
Add remaining ingredients and cook 30 min/100°C/speed 3.
Remove lemon grass stalk, add the lime juice and puree 30 sec/speed 10 or until well blended. This is quite liquid as opposed to being a paste.
Store in sterilised jars in fridge until use. This will keep up to 6 months without any problem.
