Sear the meat on all sides in a large saucepan. Add bones and fill up with water. Simmer for half an hour and add the carrots, celery and lovage. Simmer for at least 10 minutes or until the vegetables are cooked through.
Then cook the pasta in salted water and drain.
In the meantime, remove the meat, carrots, celery, bones and lovage from the broth. Let the meat, carrots and celery cool a little and dice or cut into slices. Add the pasta to the broth, season to taste and only bring it to the boil again if it is too cold.
Add meat, carrots and celery to the soup or serve in separate bowls so that everyone can take what they want.
The amount is intended for a main course. For a starter, I recommend half the amount.
