Let the salmon thaw briefly and place in a baking dish. I did it that way, but it`s likely to stay juicier when frozen.
Mix the cream with 2 teaspoons of vegetable stock, 1 teaspoon of tomato paste (so that the sauce gets a nice color and a fuller taste), some starch (so that the fat binds and the sauce becomes homogeneous) and the pressed garlic. Add a little pepper and dill and mix well (or mix up briefly).
Finely dice the shallot, sweat briefly in a little fat and add to the cream. Now distribute the sauce on the salmon in the pan and bake in the oven preheated to 180 ° C with convection for about 20 - 30 minutes.
