Put the yeast and the water in to a bowl and mix together
Sieve the flour, salt and sugar in to a bowl and mix. If you're using a mixer attach the dough hook and mix together.
Mix the yeast and water together according to instructions on the yeast packet.
Pour the olive oil and the yeast/water mixture to the bowl with the flour in it and began to mix slowly, folding the flour in on itself if you are kneading by hand. If you are using a mixer/dough hook the kneading process took approx 7 mins until it was nice and stretchy. If you are doing this by hand make a well in the sifted flour/sugar/salt mixture and slowly add the wet ingredients to the middle of the well. Folding all of the ingredients in to one another until mixed and then knead until stretchy.
When you have finished kneading the dough sprinkle some flour on to the top of the dough ball and either keep it in the mixer bowl or place it in to a new bowl if kneading by hand. Cover it with a damp tea towel and put it in a warm place for an hour or until doubles in size. The reason for sprinkling the flour on top of the dough is to stop it from sticking to the tea towel as the dough rises.
Once it’s risen remove it from the bowl and knead it further for a few more minutes on a floured surface. Then divide the dough in to four pieces and roll out to a size and thickness you prefer for your pizza.
If you're not ready to make your pizza just yet you can wrap the dough in cling-film and keep until later.
