Wash the chicory, remove the outer leaves, halve the cob. Cut out the stalk in a wedge shape. Sprinkle chicory with half of the lemon juice and place in a greased, flat casserole dish.
Wash apples thoroughly, quarter them and remove the core. Cut apple quarters into thin slices. Also sprinkle with lemon juice. Spread the apples over the chicory. Season with salt and sugar, pour on cream.
Grate the cheese and spread over it, place butter as flakes on top. Cook the casserole in the preheated oven (electric cooker: 200 °C/ gas: level 3) for 15-20 minutes. Sprinkle with chopped parsley and marjoram before serving.
