This is not your typical potato and leek soup, this one has balls due to the stock. Full of flavour and texture.
Notes: you can use stock from a supermarket but don't use stock cubes. Do yourself a favour and use the link below and make your own stock. The other thing is buy yourself a pressure cooker, I make the stock in a pressure cooker and cook it for 40 minutes.
