In a bowl, pour the flour, oil, water and a pinch of salt.
Knead quickly until you get a homogeneous ball of dough. Be careful to knead as little as possible so that the dough is not too hard and keeps its crispness, a pie dough cannot be kneaded.If the dough is too sticky, add a little flour, if it is too dry, add a little oil and/or water.
Lightly flour your work surface, spread it out and place it in the pie pan.
All that's left to do is arrange your filling and bake it (usually 50 minutes at 180°C)...
Notes
I use this dough for my savory pies as well as for my quiches or sweet pies. It's really versatile!
