Peel the potatoes and cook for about 20 minutes until they are done. Meanwhile put about 1 heaped tablespoon of salt, the butter, the marjoram and the pressed garlic cloves in a bowl.
Drain the finished, hot potatoes well and add them to the bowl. Then mash everything with a potato masher.
Gradually add the milk or cream until the puree becomes smooth. Season to taste with salt and nutmeg.
