Method

1. Soup: Place the butter in a saucepan over a moderate heat and cook the vegetables so that the onion is soft and they are without colour.
2. Gradually mix in the flour with a wooden spoon and cook slowly for a few minutes, stirring occasionally.
3. Bring the stock to a boil and gradually stir it in to the saucepan with the vegetables. Bring to the boil and add the bouquet garni and a little seasoning. Leave to simmer for 30 minutes, skimming when necessary
4. Remove the bouquet garni and add the apple and stir in the bechamel sauce. Bring it to the boil and reduce to a simmer and cook for a further 5 minutes.
5. Remove the soup from the heat and liquidise it in batches with the cream and Stilton, in a food processor or blender (be careful not to overfill it or it will spill out).
6. Return the soup to a clean pan and reheat. Adjust the seasoning and consistency by adding a little stock and cream if necessary. You should have a smooth creamy consistency, that pourable and will coat the back of a spoon.
7. Garnish: Celeriac and Apple balls: With a solorino scoop (small melon baller) remove 12 balls of both apple and Stilton, placing them in a bowl of water with lemon juice. Blanch the balls in boiling water so that they are just soft and return them to the water a and lemon juice and set aside.
8. To Serve: Heat the soup, and pour into warm soup bowls, place 2 balls of apple and celeriac in each bowl. Garnish with a little cream and chervil leaves (optional).
