Carrot & coriander Soup

This soup is so easy, I usually make it when I'm in the kitchen doing other things as it cooks itself and can just bubble away in the background!

1 tbsp butter
1 large onion roughly chopped
1 garlic clove crushed
Sprinkle of salt
4 large carrots
Water
1 vegetable stock cube
2 tbsp fresh coriander chopped roughly

1. Heat the butter and gently fry the onion for 2-3 minutes, sprinkle with salt to stop it burning. Add the garlic clove and carrots and stir into the onions
2. Cover the carrot mixture completely with boiling water and crumble in the stock cube and add the coriander
3. Bring to the boil then turn down to a simmer and cook until the carrots are soft, about 20 mins
4. Pour the soup into a blender and blitz until completely smooth. Return to the pan and heat through when ready to eat and season with salt and pepper to taste.
