Season with pepper then cover and simmer gently for one hour. 4. At the end of the cooking time, strain the stock through a sieve into a large bowl, pressing the shells and vegetables with a wooden spoon to extract as much of the juice as possible. Set aside. 5. Melt the remainder of the butter in the rinsed out saucepan then add the flour and cook over a medium heat stirring to make a roux. 6. Over a medium heat, add the strained stock a little at a time, stirring well between each addition. Raise the heat, bring to the boil then reduce the heat again and simmer gently for 15 minutes. 7. Meanwhile, in a small mixing bowl, beat together the egg yolk and cream. Set aside. 8. After the simmering time, remove the pan from the heat and stir in the egg mixture. 9.
