Dice the onion and let it tarnish lightly in a saucepan. Also dice the carrots and add to the onions. Deglaze the whole thing with the vegetable stock and simmer for about 20-30 minutes. When the carrots are soft, remove the soup from the heat and puree. Add the ginger to the soup. Season to taste with salt, pepper and paprika or chilli. Finally sprinkle with parsley and serve.
