Cut the cleaned celery into pieces, put the leaves aside, and place the pieces in the pan. Pour in the broth and cook for approx. 15 minutes until the desired firmness is reached. Thicken a little with the cornstarch and season with the spices if necessary. Chop up the leaves, add them and serve with boiled potatoes.
If you like, you can bake the dish in a fire-proof dish in the oven at 250 ° with cheese (e.g. Gouda) for 10 minutes, sprinkle with paprika powder and serve white bread! Ideal for guests!
