A traditional Colombian long soup made from three varieties of potato. Also added are corn cobs, guascas, and served with chicken, rice, avocado, cream & capers. Guascas is dried Galinsoga Parviflora or Kew weed; and it is found in Australian gardens as a weed; but commonly it is dried in Africa and Colombia to add to soups. Guascas definitely gives Ajiaco it's unique flavour. Once served, it is customary to add everything to the soup; pop in the avocado, the cream, the capers and chicken, then spoonfuls of rice.
