Put the blanched spinach in a greased baking dish, season with salt, pepper and drizzle with the olive oil. If desired, add a little garlic. Place the salted and soured fish on top and cover with a mixture of pureed parsley and garlic. Pour the salted cream on and bake at 200 ° C for 30 minutes.
Variation: Layer the shrimp or cook the shrimp at the same time. The imagination knows no limits.
