Cut the herring into small pieces, also chop the apples and cucumber and add to the herring. Cut the onions into rings and add. Pour the yogurt and whipped cream over it and mix everything together well. Season to taste with pepper, salt and a little sugar. If you like, you can also add a little oil and a little vinegar. For us personally it tastes fresher and lighter. Let soak in the refrigerator for a few hours.
In addition, you eat fresh, small jacket potatoes.
