Wash the potatoes and cook in boiling water for about 25 minutes. Meanwhile wash the meat and dab dry. Heat 2 tablespoons of oil in a frying pan and fry the meat thoroughly all around.
Fry for 12-15 minutes, turning several times. Drain the potatoes, rinse, peel and press them through a potato ricer while still hot. Season with salt and nutmeg. Add 3 egg yolks and knead everything with the dough hooks of the hand mixer.
Form approx. 20 potato balls from the dough (sticks a little bit on the hands). Whisk the eggs. Mix almonds and breadcrumbs. Turn potato balls one after the other in flour, egg and almond and breadcrumbs mixture.
Put the balls in cold storage. Grate cheese. Mix cheese, 1 egg yolk, marjoram and cream. Clean and wash the broccoli and cut off the florets. Season the meat with salt and pepper, take it out of the pan and put it on a baking tray lined with baking paper.
Cover each with 2 slices of ham and spread the cheese mixture on top. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 12 minutes. Put broccoli into boiling salted water and cook for about 10 minutes.
In the meantime, heat 1 litre of oil in a high pot (180 °C). Fry the balls in portions in the hot oil for about 2 minutes. Keep warm. Arrange the meat on a plate garnished with marjoram.
Add potato balls and broccoli extra.
