For sauerkraut with apple and bacon, cut the bacon slices into small pieces and fry a little.
If there is not enough fat, heat some lard, add the onion and let it color a little. Roughly grate the apples and let them fry as well.
Pour in the soup, add the cabbage, cover and simmer until soft. If necessary, place a few juniper berries, a bay leaf and 2 cloves in a tea ball and simmer until tender, stirring regularly.
If necessary, pour some more soup, remove the spices and serve.
