Preheat your oven to 180 C/350 F/Gas Mark 4. Snip the bacon into small strips if needed. Use the 1 tbsp oil to fry the 200 grams of bacon. I like to get some browning to them. If a lot of water pools in the frying pan. Remove it so that the bacon doesn't boil.
Set aside and start the pastry. If using a food processor then put the 300g flour, 150g cold butter (cut into 3 cm chunks) and 1 pinch of salt into the processor bowl. Pulse until you get a breadcrumb effect. If doing it by hand then go ahead and rub the ingredients together. Add 5 to 6 tbsp of cold water and pulse or mix together until dough begins to form into a ball. At that point tip it out and use your hands to bring finally together into a smooth dough.
You can cover and chill the pastry at this point but I seldom do. Lightly flour your work surface and roll out the pastry to roughly a 30 cm circle. The pastry should be about 4mm thick. You will have some left over but it makes the job easier! I make a few jam tarts with the left overs.
Use the rolling pin to transfer the pastry to the dish and gently line it. I use the rolling pin to remove the overhang of pastry by rolling it over the edges. Prick the pastry base with a fork all over, line with baking paper or a reusable cake and fill with baking beans or similar. Bake for 25 minutes.
Remove from the oven, remove the liner and beans ( be careful as steam can gather under the liner) and brush the bottom with some of the beaten egg to seal all the holes. Put back in the oven for another 5 minutes.
Combine the 280 g of cream cheese, remaining pinch of salt and 3 beaten eggs until smooth. Add 5 or 6 twists of black pepper.
Putt the bacon and 100 g of grated cheese in the bottom of the pastry case and pour over the egg mixture. Bake for about 30 minutes until golden and scorched in parts. Leave to cool a little before serving. It'll rise like it's so very proud of itself.
