Wash the potatoes and cook in lightly salted water for about 25 minutes. Drain the potatoes and let them cool down a bit, then peel them and press them through the potato press.
Season the mashed potatoes with herb salt, pepper and nutmeg. Stir in the butter, fold in the cream cheese mousse and add some cream, possibly some milk.
Season the mashed potatoes to taste, garnish with a little lovage pesto and serve.
