This is an original and tasty dish, ideal for using up leftover celery (those heads are always a little large to use up in one go…) It tends to come out creamier using spelt flour to coat, but wheat flour is fine too.
For a protein-rich one-dish meal, add seitan pieces at the end (when you add the stock).
