Sweet Potato Soup

Saw a recipe for sweet potato soup on the Good Food web site and thought this would be good for cold evenings.  As usual I tweaked it a little when I started to make it.

Ingredients:
2 medium size sweet potatoes (725g) peeled and grated
2 medium onions (320g) peeled and grated
1 large apple peeled, cored and grated
100g dried red lentils
3 cloves of garlic chopped
3 Tbls olive oil
5 cups (1.25l) vegetable stock using 3 veggie Oxo cubes
1 cup (250ml) of soya milk

Fresh coriander
4 tsps cumin
1 tsp ground ginger
1 tsp turmeric
1 tsp paprika

Method:
1.  Heat a deep heavy sauce pan over a medium heat
2.  Add the olive oil
3.  Add the onions, garlic and apple
4.  Add the cumin, ginger, turmeric and paprika and stir together
5.  Replace sauce pan lid and cook for 5 mins
6.  Add the stock, sweet potato and lentils and stir to combine all the ingredients
7.  Replace the lid and simmer for 15 minutes (stirring occasionally)
8.  Once all the vegetables are tender, add the milk
9.  Stir in the milk, replace lid, then remove from the heat. 
10. Let stand for 5 mins with lid on.
11. Using a hand blender or food processor, blend soup mixture until nice and smooth
12. Add a handful of chopped fresh coriander before serving

This made enough for six to seven large bowlfuls.
