Chop the turkey meat, season with pepper, salt and fry briefly on all sides in hot oil. Remove the meat and sauté the onions in the roast.
Stir in the garlic, paprika powder, mustard and tomato paste, immediately add the chicken stock and white wine. Season with sugar, nutmeg and caraway seeds, add the meat and cook covered (approx. 20 min.) Until soft.
Remove the turkey pieces, mix the creme fraîche with the stock and, if necessary, thicken with flour. Season with salt, lemon juice and a little lemon zest and add the meat again. I recommend spaetzle as a side dish.
