Let the milks soak in hot - not boiling - water until they are done (takes about 20 minutes).
Sear the veal. Add the finely chopped onions and mushrooms and sauté. Add the flour. Fry briefly. Then deglaze with the white wine and the stock and boil down until the meat is cooked through. Add the milk and the cream of the sauce. Season to taste with salt, pepper, nutmeg and paprika powder.
Now remove the lid from the patties and bake the patties (with the lid) in a hot oven at 200 ° C for about 10-12 minutes.
Arrange the patties on plates, fill with the sauce and put the lid on. Serve the rest of the sauce as you like or alternatively drape it over rice or mashed potatoes (mashed potatoes).
Tips: You can easily use leftover meat for the sauce. Often the milks are also replaced by veal roast. Add the cooked meat to the sauce together with the milk.
The patties can also be made from puff pastry yourself. To do this, roll out approx. 500g of puff pastry and cut out roundels. A patty consists of a base, a rim with the same diameter and a lid that is cut out of the rim. Pre-bake the patties for about 20 minutes at 220 ° C.
