Chicken simmered in broth with potato, carrot and peas for forty minutes, then pasta added at the end. Fifty-five minutes, five servings, and the pasta goes in last for a reason.
The pasta goes in at the end and that is the whole structure of the soup. Half a cup of pasta in seven cups of broth needs eight to ten minutes; the chicken and the vegetables need forty. Put them in together and the pasta dissolves into the broth long before the chicken is done. It also means the soup does not keep well. Pasta carries on absorbing liquid off the heat, so a pot left standing turns into something much thicker, and by the next day the shapes are soft and the broth has gone. If you are making it ahead, cook the pasta separately and add it to each bowl. What Colombians call color is a powdered achiote or annatto colouring, sold in sachets, that turns a broth golden. It contributes almost nothing to the taste. A pinch of turmeric or sweet paprika does the same. The chicken is marked optional, and without it this becomes a vegetable soup that takes far less than forty minutes: give the potato and carrot fifteen and go straight to the pasta.
