Hake and shrimp cake, a Christmas recipe with fish as the protagonist

On Christmas Eve, many people spend hours and hours in the kitchen. Much of the work that later decorates the Christmas tables requires time, work that is not always seen and valued. If this year you want to prepare a dish that does not require cooking on the same day, try this hake and shrimp cake. You can cook it beforehand and let it cool in the refrigerator, but you will have to make the sauce at once.
