Steaks with Mashed Jerusalem Artichokes
Peel and coarsely chop the Jerusalem artichokes. Cook in a pot of boiling water until knife-tender, about 30 minutes. Drain the Jerusalem artichokes, add to the warm pot and allow the excess moisture to evaporate. Gently heat the butter with the cream and milk in a pot on the stove. Pour over the Jerusalem artichokes and mash until creamy. Season with salt, pepper and nutmeg to taste.
Peel and quarter the onion. Season the steaks with salt and pepper to taste. Heat the oil in a grill pan. Add the steaks and sear each side until golden. Remove and place in a baking dish along with the onions. Bake in a 120°C (approximately 250°F) oven for 10 minutes or until desired doneness is reached.
Serve the steaks with the Jerusalem artichokes and onions.
