For the sauce, add the * sour cream - made easy, the gypsy sauce and cooking cream in another bowl. Mix these together and put them in the roaster (oven master) and mix everything again.
Close the whole thing with a lid and put it in the preheated oven and cook / stew for about 70 minutes. After this time, season the whole thing again, season if necessary and sprinkle with freshly chopped parsley. I served that with ribbon noodles.
