Cauliflower,parsnip and potato soup

This delicious thick and creamy soup is adapted from a thermomix recipe.  See those instructions at the end.  The parsnip adds a beautiful nutty flavour. 

Ingredients:

oil

1 medium onion

2 cloves garlic (optional)

3 potatoes

1 small or 1/2 large cauliflower (I used the beautiful romanesco pictured)

1 small parsnip or 1/2 large

approx 750ml water or stock

salt

20g butter

2 tbs flour (corn flour if gluten free)

Method: 

Dice onion and garlic and fry in oil in a large saucepan.  Chop potatoes, cauliflower and parsnip into bite size pieces. Add to the saucepan with water/stock and salt.  Cook for approximately 20 mins until vegetables soft.  Add butter and cook for a few more minutes.  Blend and serve with a spring onion garnish.
