Peel and wash the potatoes and celery and cut into large cubes. Boil the potatoes and celery in salted water and cook for about 30 minutes. Meanwhile roast almonds in a pan without fat until golden brown, take them out. Wash the meat, dab dry and cut each cutlet into three. Whisk the egg in a deep dish. Mix flour with salt and pepper in a deep plate. Turn the schnitzel first in flour, whisked egg and then in breadcrumbs.
Heat the oil in a large pan and fry the escalopes on both sides for 3-4 minutes at medium heat. In the meantime heat milk and 25 g fat. Drain the potato-celery, add the milk and mash with a potato masher. Foam 15 g fat in a small saucepan. Arrange celery-potato puree and schnitzel on plates. Sprinkle the puree with almonds and drizzle with fat. Garnish schnitzel with cranberries and thyme
