Wash the meat and dab dry. Cut larger pieces in half. Fry the meat in hot lard in portions. Season with salt, pepper and paprika and dust with flour. Sauté well and deglaze with wine and 3/4 litres of water.
Cover and cook for about 1 hour. Clean, wash and cut the leek into rings. Add during the last 15 minutes. Wash, pluck, halve and core the grapes. Add to goulash 15 minutes before the end of cooking time.
Season again and serve. Spätzle are delicious with it.
