Wash the chicken inside and out under cold running water and pat dry with kitchen paper. Mix a little salt, pepper and curry and season the chicken with it. Tie the legs together with kitchen string.
Place it with the chest side down in a roaster rinsed with water. Spread flakes of fat on the chicken. Roast in the preheated oven (electric: 200 °C/ gas: level 3) for 50-60 minutes.
In the meantime, drain the corn and cut it into wheels. Clean and wash the celery and cut it into 2-3 cm long pieces. Drain the plums and collect the juice. Halfway through the frying time, turn the chicken and spread the vegetables and plums around it.
Sprinkle with salt and pepper. Pour in the chicken stock and finish frying the chicken. Add some plum juice and curry to the roast stock to taste.
