Two very similar versions of this recipe exist: one in Denmark and one in Landes, in southwest France. In both cases, it is served with grilled or roast pork or sausages.
Clean cabbage. Slice the cabbage into 3-inch strips.
Slice the bacon into 1-inch squares.
Put a thick-bottomed pot on medium heat. Add bacon and sauté a few minutes until they render their fat. Add mustard seeds. When they begin to sizzle, add cabbage strips, sage, bay leaves, salt, pepper, nutmeg and orange zest. Stir well.
Grate apples and add to the pot. Add wine, vinegar and maple syrup; incorporate. Reduce heat to low after about 5 minutes. Let steam in the pot until vegetables are tender, 20-30 minutes.
Let stand a few more minutes before serving.
