Cod With Spinach

Preparation:

Preparation: Wash the spinach in several water, cut the stems and, after having drained them, blanch them in boiling salted water, remove them from the heat and drain them. Also blanch the cod that you previously left to soak in water for a long time to soften it and to make it lose all the salt. Separately, cut the stem and carefully wash two bunches of sorrel and add it to the spinach. Then take a baking dish, butter it and put a layer of spinach and sorrel mixed together on the bottom, then put the fish cut into regular pieces on top and cover with another layer of spinach and sorrel. Sprinkle everything by pouring the melted butter over it and place the pan in the oven, cooking over moderate heat for about thirty minutes. Serve hot. If you don't like sorrel, you can remove it and leave the spinach alone, flavored with a little cheese.
