Locro is a traditional recipe from Argentina which is a cross between a hearty stew and a cassoulet. This version combines firm white fish wih well cooked potatoes. (Cooking times are estimated.)
Melt the butter in a large saucepan and add the paprika, stirring to mix in the spice. Sauté the onions in this mixture until soft.
Add the water and bring to a boil; add the potatoes. Simmer gently until the potatoes are almost cooked. Depending on the size of the potatoes, it may be necessary to add more water during cooking.
Add the light cream and the fish and continue cooking, stirring occasionally, until the potatoes begin to fall apart. If necessary, take the back of a large fork or wooden spoon and gently mash the potatoes.
Add a little of the potato mixture to the beaten eggs and then add the eggs to the soup. Remove from the heat, stir in the cheese, correct the seasoning, and serve at once.
If available, some roasted corn kernels can be sprinkled on top as a garnish.
