Melt the butter in a large pot and sauté the onion until soft. Add the cabbage and apple and cook for about 5 minutes.
Pour in the Riesling, vinegar and brown sugar, then add the cinnamon, cloves, salt and pepper. Cover and simmer gently for 35–45 minutes, stirring occasionally, until the cabbage is tender and the flavors have come together.
Pairs naturally with bratwurst, schnitzel, pretzels, roasted potatoes, or vegetarian sausages
