Pour water and olive oil into a large bowl.
2 cups lukewarm water, 1/4 cup extra virgin olive oil
Add the sourdough starter and mix together.
1 cup sourdough starter
In a separate bowl mix the flour and salt together.
5 cups bread flour, 3 tsp salt
Add the flour/salt mixture to the large bowl.
With your hand or wooden spoon, mix all the ingredients until it comes together as a sticky ball. Tip: Wet your hands to work with the sticky dough.
Dust the dough with flour and cover with glad wrap and a tea towel.
Put the bowl in a warm place.
Every 30 minutes (4 times), stretch and fold the dough, remember to have a small bowl with water nearby to wet your hands.
Once the dough has doubled in size (after around 5 hours), tip it onto a dusted workbench.
Cut the dough into 5 equal parts if you make individual pizzas or two big pieces if you bake them on a baking sheet.
Shape the dough into balls, cover them with a tea towel, and let them rest for another 20 minutes.
Dust your pizza pan with some flour and stretch the dough out to the required size.
