Put the flour, salt, and roughly chopped butter into a bowl and combine until it resembles coarse breadcrumbs:Food processor: Process for 5 secondsStand or hand mixer: Mix on medium for 1-2 minutes (longer for smaller mixers)By hand: Rub the butter through the flour mix for about 5 minutes
Add the egg yolk and 30ml water and blend again, or mix with your hands until the mixture starts to form a ball. You may need to add extra water to get it there.
Gather the pastry together in your hands and knead two or three times until it is a solid ball that isn't crumbly (not enough water) but doesn't feel slimy (too much water)
Cover the pastry ball in clingfilm, or put it in a plastic bag or box with a lid, and put in the fridge for at least 30 minutes before you use it (see tip)
When you're ready to use the pastry, preheat the oven to 200°C/ 185°C fan/ gas mark 6/ 400°F
Press the pastry into the flan dish with your fingers
To bake the pastry case without a filling (blind): put some baking parchment on the bottom and add dried beans or ceramic baking beans to weight it down.
Cook for 10 minutes. Remove the beans and cook the pastry case for another 10 minutes
Cool on a wire rack or fill for further cooking according to your recipe.

Notes
Everyday Cooks tips:
Make at least double quantities, line the flan dishes, cover with clingfilm, and freeze - either cooked or uncooked
Make the pastry up to 48 hours before use and leave in a ball in the fridge
Make the pastry and line the dish the day before you want to use it. Cover with clingfilm and store in the fridge
If your blind-cooked pastry case has holes in it, you can patch them with left-over pastry. This is only essential if you have a loose-bottomed flan tin.
Invest in china flan dishes of varying sizes. Your quiches will always look good and you save time and effort with this method
