We clean the anchovies from bones. We clean the vegetables and chop them into large pieces. We put water in a pot, add the fish and vegetables and let them boil, about 25-30 minutes. Then, we strain the broth of the soup. In the same pot, we melt the butter and oil, add the flour and fry. until it turns golden brown. Then, we add the broth of the soup that we left aside, mix it with a wire whisk, try to bring it to the consistency, and let it boil. After it boils, we add the fish that we left aside, the chopped vegetables, spices and lemon juice and boil for another 10 minutes. This much. very healthy and super delicious
