Spiced Kumara Soup

I had lots of Kumara (orange sweet potato) in the pantry that needed using up and made this the other night - very good. (a variation of the chickpea soup from the Varoma demonstration)

100g dried chickpeas, milled for 30 seconds in TM on speed 9
Olive oil
1 onion, quartered
1 clove garlic
1tsp ground coriander
2tsp ground cumin
1/2 tsp ground chilli, or to taste
600g kumara, peeled and chopped
150g carrots, peeled and chopped
1-2 tblsp TM vegetable stock
1000g water
1/2 small lemon
Natural yoghurt to serve

Chop onion and garlic on speed 7 for 4 seconds.
Add 30g oil and saute at 100 C for 2 minutes on speed 1.
Add spices and cook for 1 minute at 100 C on speed 1.
Add vegetables, stock, water and dried chickpeas and cook for 25 minutes at 100 C on speed 1.
Check vegetables are cooked, then puree by slowly turning speed dial from speed 1 to speed 9 for 30 seconds.  Add lemon juice and blend for 10 seconds on speed 5.
Serve and add spoonful of yoghurt, if desired.
Serve with parathas (from Indian cookbook)
