Catfish simmered with potato, corn, green plantain, cassava and arracacha. Those last three are what make it a sancocho rather than a fish soup. An hour, and it feeds five.
Arracacha is the ingredient that makes this a sancocho and not a fish soup, and it is worth knowing. It is a root related to celery and carrot, sold in Latin markets as arracacha or apio criollo, with a texture between potato and parsnip and a distinct celery-like sweetness. Grated into the pot, it dissolves and thickens the broth. If you cannot find it, parsnip is closer than potato, though nothing tastes quite the same. The fish goes in last, with the potatoes, and gets 20 to 25 minutes. Everything else needs longer, which is why the plantain, cassava and corn go in at the start. Catfish holds together well; a softer fish will break up. What Colombians call color is a powdered achiote or annatto colouring sold in sachets, not the artificial food colouring the old translation suggested. It turns the broth golden and adds little flavour. Turmeric does the same job.
