Turn the oven to 180C fan/200C. This is easier to handle and cook with than sweet, as it is the sugar in sweet, that makes is difficult. Again I would always make a large amount and freeze half. If you want to make it more savoury, you can add two teaspoons of fresh parmesan, very finely grated.
1 pack of unsalted butter (250g), room temperature, cut into cubes.
1 small pack plain flour (500g)
Pinch of salt
2 Medium Eggs
2-3 tbsp cold water
Put all the ingredients in a Magimix and blitz until it comes together into a ball. Turn it out and kneed it gently to ensure it has all come together properly- this should take no more than 30 seconds. Cut it into the quantities needed and freeze the rest, wrap in cling film and put the half you are using in the fridge for at least 30 minutes.
The Cling Film Trick
Grease the tart dish with a little butter all round. Take cling film put it on a surface, make it larger than the tart dish double sided. Work the pastry a little in your hands to make it an even round. Put the pastry in the middle of the cling film. Put cling film on top, same size again. Then roll the pastry between the cling film. Don’t flour the cling film, this stops the trick working. Once it is to size (an inch larger than the dish all round), take off the top cling film. Put the middle of the pastry open side down in the tart dish and gently push it into the sides. There should be overhang of pastry all round (this is good). Take the cling film off the top of the pastry carefully and then fold the overhanging sides down. Check for any tears and fix them with extra pastry (cut off bits, etc.). Prick it round with a fork. Put it is the fridge for at least 20 minutes.
Bake it blind
Take the pastry out of the fridge, get some baking parchment and put it in the pastry and fill with baking beans. Bake it in the oven for 10 minutes (until the sides are beginning to colour light brown). Then take out the beans and bake for another 10 minutes until it is crisp. Then get an egg yolk and a dash of milk, mix together and paint onto the pastry. Bake for 2 minutes to seal the pastry. Finally, run a sharp knife around the top of the pastry at the flat with the edges of the tart dish. This gives a perfectly even edge and gives the kids the overhanging and very crispy pastry bits to eat in the meantime.
