Boil the unpeeled potatoes as jacket potatoes for approx. 15 minutes. Peel off and let cool. Meanwhile, cut the pork loin into approx. 1.5 cm thick slices. Make a sauce from the cream, sour cream and crème fraiche and season with the spices.
Place the Kassel slices on a greased tray. Roughly grate or grate the potatoes and spread over the meat. Pour the sauce over it and bake the tray in the preheated oven for approx. 1 hour at 200 ° C. Scatter the cheese over it 10 minutes before the end of the time so that it does not burn.
A fresh salad is best served with it.
Note: There is no indication of the amount of cheese, as some prefer to use more cheese for gratin and others prefer a little less. This dish is great to prepare. We did it on New Year`s Eve and all guests loved it.
