All you do is sift the flour into a large mixing bowl, add the spring onions, two-thirds of the crumbled cheese, the cayenne pepper and the salt.
Then, using the coarse side of a grater, grate in the celeriac as well. Now give everything a really good mix. Beat the egg and milk together and, using palette knife to mix, gradually add it all to the mixture until you have a loose, rough dough.
Now transfer it to the baking tray and, still keeping the rough texture, shape it into a round with your hands. Next, lightly press the rest of the cheese over the surface, sprinkle with a little flour and bake the bread on the middle shelf of the oven for 45-50 minutes, or until golden brown. Cool on a wire rack and eat as fresh as possible.
This is lovely served still warm, and if you have any left over, it's really good toasted.
Pre-heat the oven to gas mark 5, 375°F (190°C).
