Clean, wash and halve the cabbage and cut it into cubes from the stalk. Cut tomatoes into strips. Heat the fat in a frying pan, add potato noodles and fry for 15 minutes while turning.
After five minutes coarsely grind the ground pork fat and add it. After another five minutes, add cabbage and tomatoes and continue frying at reduced heat. Stir the sour cream and stock until smooth and add just before the end.
Season to taste with salt, pepper and nutmeg.
