Baden Leek Soup

This recipe comes from Baden Baden the well-known German health spa and it is a nourishing comforting soup. The ‘honest toun’ of Musselburgh where I live is famous for its leeks, even the ancient Romans praised and exported Musselburgh leeks. It was only in this century that the species was registered and named by the great botanist and horticulturist, Mr Scarlett. It is a soup I often make with our excellent leeks.
