Wash the meat. Soup greens clean or peel, wash and roughly chop. Bring everything to the boil in a pot with bay leaf, peppercorns and a good 1 l water. Simmer at medium heat for about 1 1/2 hours. Skim in between
Let the meat cool down. (Use broth e.g. for a "slim" bouillon.)
Peel the onions. Drain the beetroot and collect the stock. Dice onions, beetroot and cucumber. Peel, quarter, core and chop apples
Mix salad cream, yoghurt, cucumber water and 4 tablespoons beetroot stock. Season to taste with salt and pepper
Wash herrings, pat dry and cut into pieces. Dice meat finely. Mix prepared salad ingredients and salad cream, season to taste. Coarsely chop the nuts and sprinkle over the salad. Wholemeal bread tastes good with it
