Steam the onion (s) in butter until soft, deglaze with the cream and milk. Stir in 1 tablespoon instant vegetable stock and tomato paste. Season to taste with dill, salt (carefully!), Pepper and paprika (sweet and hot).
Place the salmon in a greased baking dish and pour the sauce over it. Bake in the oven (fan oven 200 °, top and bottom heat 180 °) for about 15 minutes.
Control fish: if it breaks apart when you want to pick it up, it`s done. If not, give it a few more minutes.
In addition, (fresh, green) ribbon noodles taste very tasty.
