Sourdough Pizza Base

I have been trying out a few new sourdough pizza base recipes and I am happy with this improved version.
Simplicity and versatility are high on my list and this one ticks both those boxes.
Its a great way to use up discarded starter or can be made with active starter too. 
The addition of semolina and a few tablespoons olive oil make all the difference to the flavour and texture.
A few tips for a nice crisp base, preheat your oven to high and preheat your baking tray. This can make it difficult to transfer your pizza but using a pizza paddle to literally slide it on works well.
To be honest I just preheat the oven then put the pizza base on a cold tray then add the toppings, its easier and I don't have a pizza paddle!

So here is my recipe
Ingredients for 4 large or 6 medium pizzas
500g pizza flour or plain flour
300g starter or discard
250 ml warm water
2 tablespoons olive oil
50g semolina or fine polenta
10g salt, 2 level teaspoons

Method
Measure the flour, semolina and salt into a large mixing bowl.
Mix the warm water with the starter and oil in a jug.
Add to the dry mix in the bowl and knead until it comes together into a fairly smooth ball. Takes around 5 minutes.
Cover with a tea towel and leave at room temperature for a few hours until roughly doubled in size.
Put the dough onto a floured surface and use your knuckles to knock the air out of it.
divide the dough into 4 or 6 pieces depending on the size of pizza you want.
Roll out thinly, add toppings and bake in a hot oven for around 15 minutes until the base is crisp and golden.

I had extra dough so just put it in the fridge in a tupperware dish and used it the next day to make pizzas for lunch.

Alternatively you could make the dough in advance and just leave it in the fridge until you need it, bearing in mind it will become more sour the longer you leave it! I imagine it would be ok for 2 or 3 days!

If you don't have sourdough starter then you can use instant dried yeast, here is the amended recipe.

Standard Pizza Base
500g plain or strong white flour
1 1/2 tsp salt
1 tsp instant dried yeast
325 ml warm water
1 tablespoon rapeseed or olive oil

Method
Put the flour in a large bowl with the salt and yeast.
Add the oil and water and knead for 5 to 10 mins, until smooth.
Put the kneaded dough in a lightly oiled bowl, cover with a tea towel and leave in a warm place for a couple of hours, until roughly doubled in size.
Proceed as sourdough recipe.
