In a large bowl, whisk together the flour and salt.
Pour in the olive oil and 60 ml (4 tbsp) of the cold water, then work the ingredients together (I used a stand mixer).
Gradually add more water, a little at a time, until the dough comes together. You’re aiming for a soft but not sticky healthy pie base. Be patient, letting each addition of water fully absorb before adding more. Your dough should be soft but not sticky.
Shape the dough into a rough ball, wrap it in clingfilm, and rest in the fridge for 20–30 minutes. There is no butter, so it won’t firm up like a butter-heavy dough, but the resting allows it to roll out much better.
Preheat the oven to 190℃ (375℉).
Roll out the dough on a lightly floured surface until it fits your pan (mine is 28 cm) with a slight overhang.
Press the dough into the pan (no need to grease or line the pan), and trim the edges slightly, leaving some extra to account for shrinking.
