Boil up approx. 2 l salted water with 1 tbsp vinegar. Clean, peel and wash the celery and cut or slice it into strips. Simmer in boiling salted water for about 5 minutes. Drain, rinse with cold water and let drain.
Peel, wash and roughly grate the carrots. Coarsely chop nuts and roast them in a pan without fat until golden brown. Let them cool down. Drain the mandarins and collect the juice.
Stir mayonnaise, cream and 100 ml mandarin juice until smooth. Season to taste with 3-4 tbsp vinegar, salt and pepper. Mix celery, carrots and salad dressing. Fold in tangerines and nuts. Season salad. Wash parsley, shake dry, chop and fold in just before serving. Serve with farmhouse bread.
