Peel and boil the potatoes, and then let them cool down. When the potatoes are cold enough cut them in medium size pieces that you like to have them in your salad. Put them in a big bowl.
Peel and cut the apples and the red onion and garlic clove in the desired sizes, and add them in the bowl with the potatoes.
Wash and cut the chives, leek and dill in thin slices, and then pour them in the big bowl with the potatoes and the apples and onion.
Mix the sour cream and the creme fraiche in a bowl, and add the salt and pepper and stir it together.
Pour the cream in the bowl with the rest of the ingredients and mix it well together. Place the salad in the fridge for a few hours before it is time to serve.
