The next day, take the poolish out of the fridge & leave to sit at room temperature for 1 hour.
In the meantime, place the flour, water & olive oil into the bowl of a stand mixer. Mix with the dough hook until just combined then leave to autolyse for an hour.
Next, pour the poolish into the dough & mix on a medium speed until incorporated. Add in the salt & continue mixing until the dough passes the windowpane test. This will take 10-15 minutes on a medium speed.
Cover the bowl with clingfilm (or a tea towel) & leave at room temperature for 1 hour.
Next, tip the dough out onto a clean worksurface, divide into 5 even pieces then shape into balls. Each ball of dough should weigh around 260g.
Lightly oil 5 round storage containers then place a ball of dough into each.
Place in the fridge & leave to ferment for 36-48 hours.
Take the dough out of the fridge 1½ - 2 hours before using for pizza.
To make into pizza, first tip the dough out onto a floured worksurface then flip over so that the dough is facing the same was as it was in the container.
Using your fingertips, press the dough into a disc. Starting from the centre & working to the edge, making sure to leaving a 1-2 cm border (this will be the crust).
To stretch, I like to use a method know as "The Steering Wheel" stretch. Here's how...Using both hands, pick the dough up from one edge & hold it in front of you like a steering wheel. Now rotate the dough in your hands, pinching to form a crust as you do so. As the dough rotates, gravity will stretch it into a large circle. With this method you have full control on the thickness of the crust. If you'd prefer a thinner crust, pinch the dough nearer the edge. For a thicker crust, pinch more towards the centre. Top the dough with a light layer of toppings then cook in a pizza oven at 400°c - 450°c (750°f/840°f) for 1-1½ minutes turning regularly with a peel to stop it burning.
