Hake is a low-fat, low-bones and very useful fish. It can be cooked in various ways, but a particularly tasty fish is obtained if it is baked in foil with onions and lemon. The hake fillet prepared in this way is particularly tasty and fragrant, and the foil keeps all juices and does not allow the fish to dry. Thanks to the butter, the baked hake becomes very juicy and gentle. As a side dish, mashed potato, rice or fresh vegetable salad will be excellent.
