Colombian Ajiaco

• approx. 2 kg (4 lb) free-range or organic chicken
• 2 large onions, peeled and quartered

Rinse and dry the chicken, and remove any cavity fat. Put the bird in a large saucepan with the onion, coriander stalks and water. Add more water if necessary, to cover the chicken. Bring to the boil, remove any scum from the surface, cover, and simmer gently for 15 minutes. Add the soft-cooking potatoes, and cook for a further 25 to 30 minutes. Remove the coriander and onion and discard. Take
