Chop the vegetables into bite-sized pieces. Cut the pork belly into fine strips and the beef into walnut-sized pieces.
Put clarified butter in a large saucepan and fry the meat with the bacon in it all over. Add the vegetables. Season with tomato paste, bay leaves, allspice, juniper, salt and pepper and then deglaze with the vegetable stock. Now fill with water or broth until everything is covered and simmer for approx. 2 - 2.5 hours without a lid.
Serve the finished borscht with a dollop of sour cream, freshly chopped herbs and chopped spring onions.
