For the stifado, peel and roughly dice the onions. Peel garlic and chop finely. Wash the lemon hot, dry and grate the peel. Wash and coarsely dice the tomatoes.
Dab the goulash dry. Heat 3 tablespoons of oil in a roasting pan or large casserole and fry the meat in 2-3 portions until it is brown all around. Season with salt and pepper. Finally fry onions, garlic and lemon peel for about 5 minutes.
Add all the meat and tomatoes. Season with salt, pepper and pimento. Add cinnamon sticks and bay leaves.
Dust the stifado with flour and sauté briefly. Deglaze with wine and 1⁄2 l water and bring to the boil. Cover and braise over medium heat for about 2 hours. Stir occasionally during the last 30 minutes.
Preheat oven (electric cooker: 225°C/circulating air: 200 °C/gas: see manufacturer). Peel, wash and cut potatoes into thick slices. Mix well with 3 tbsp. oil and approx. 1⁄2 tsp. salt. Place potato slices close together on a baking tray.
Bake in a hot oven for about 30 minutes.
Season the stifado with salt, pepper, pimento and lemon juice. Serve with the baked potatoes.
