What is celeriac? For those of you who don't know, it is the large root bulb of the celery plant. This is why this soup tastes like a sort of much creamier and thicker celery soup. It's a very good winter soup because it's especially thick and warming. It has a look of semolina when its out. The root can be hard to peel, it's best to cut it in half but maybe peel it with a potato peeler first. Then cut chunks off it. Don't make the chunks too large because you want them to cook through. If you smell it it does have a slight celery smell, though it does look like an old skull or something from Doctor Who, with the tendril bits coming off it. Try it out, I am sure that you will like it, and it's the crusty rolls yet again to serve....
