Fry the onion in a frying pan for 1 minute in melted butter (30 grams). Make mashed potatoes from boiled potatoes, butter (30 g) and milk. Add a pinch of nutmeg and ground pepper.
Add cabbage and onion to the puree.
Place on a platter with a slide, make a recess in the center and pour the remaining melted butter there. You can decorate with greenery.
Enjoy your meal!
