Cook the peas in boiling salted water for 2-3 minutes. Drain, rinse with cold water and let drain. Clean, wash and cut spring onions into rings, if necessary put some spring onion ends aside for garnishing. Wash and drain the salad and cut into strips. Cut the trout into pieces. Wash the dill, dab dry and chop finely.
Mix dill, salad cream, milk and lemon juice. Season to taste with salt and pepper. Put salad, peas, salad cream, trout and spring onions in 4 glasses. Garnish with set aside spring onions. Pumpernickel tastes good with it
