Fry the ham in a hot pan (preferably a coated one) without any additional fat. If the roasting fat has settled in the pan, add the onion cubes and fry briefly. Put the drained sauerkraut in the pan and sear it. So that it doesn`t burn too much, add a little butter or margarine from time to time. When the whole sauerkraut is brown, add the sugar to taste and stir everything again well.
We usually make smoked pork or sausages with boiled potatoes.
Of course, it can also be prepared meatless and / or refined with canned pineapple pieces.
