Season the steaks with cumin and black pepper. Roll them in flour and braise them for 1-2 min. on each side.
Move them to a tray, and in the same oil braise the chopped potatoes and garlic. Add the resulting mixture to the steaks.
Meanwhile, mix the milk and yoghurt, cream and flour.
Add the resulting mixture to the veggies and stir. Cover the products in the tray with this sauce. Bake everything for about 40 min.
