A Colombian soup of potato, cassava and papa criolla in chicken broth, finished with thin egg omelettes cut into strips. The tortillas here are made of egg, not corn: this is not Mexican tortilla soup. Serves six.
The tortillas in this soup are egg, not corn. They are thin omelettes made in a separate pan and cut into strips, and they go in at the very end: two minutes is enough to warm them, and longer makes them rubbery and cloudy in the broth. Make them while the soup simmers so nothing waits. If you cannot find papa criolla, use baby Yukon Gold, though the broth will be paler.
