Place the onion and garlic into the Thermomix bowl and chop for 3 sec/speed 5. Scrape down the sides of the bowl with a spatula. Add the olive oil and saute for 5 min/100°C/speed 2 without the measuring cup.
Add the carrots and chop for 5 sec/speed 5. Scrape down the sides of the bowl.
Add the ground coriander and vegetable stock and cook for 10-12 min/100°C/speed 1 with the measuring cup on.
Once finished, check that the carrots are soft and cooked through. If not, cook for another couple of minutes or so. Add the fresh coriander and blend for 1 min/speed 9, slowly increasing the speed - be extra careful if you have the old TM31.
Check for seasoning and consistency - add a little more stock or water if desired. Serve immediately with a sprinkling of fresh coriander.
