* 1 Egg yolk, beaten
* 160g Cheddar cheese, cut into small cubes
* 110g any semi-hard Blue cheese, Grated or crumbled
* 4 very large Eggs, beaten
* 200ml Milk
* Seasoning
* 110g any hard Cheese, Grated

===Method===
* Line the flan tin with the Pastry.
* Prick holes with a fork all over the bottom and Refrigerate for 30 minutes.
* Preheat the Oven to 200° C (400° F - gas 6), [fan oven 180° C & reduce cooking time by 10 mins per hour].
* Bake blind for 20 minutes.
* Brush the beaten Egg yolk over the base so that the fork holes are covered.
* Return to the Oven, and Bake for a further 7 minutes.
* Remove from the Oven and leave to cool.
* Once cool, scatter the cubed Cheddar over the base.
* Mix the Blue cheese with the Egg, Milk and seasoning and pour over the Cheddar cheese.
* Bake at 190° C (375° F - gas 5), [fan Oven 170° C & reduce cooking time by 10 mins per hour] for 40 minutes.
* At this stage the mixture may still be unset, but that is fine.
* Sprinkle the Grated hard Cheese evenly over the top and Bake for a further 10-20 minutes until the Cheese starts to Brown.
* During this period, it may rise like a soufflé, but it will soon revert to normal during cooling.
* Allow to cool to room temperature before serving.
