Mix yeast, sugar with warm water and set it aside for 5 min or till it foam up.
Take flour in a bowl and mix salt with it. Add the yeast water with the flour mixture and make a soft dough. Apply oil all over it generously and cover it. Cover it with a damp cloth and Set this aside in a warm place till it doubles in size( for about 1 hour).
When it doubles,knock out the air and knead the dough for 3 min. Add extra flour if you need. Now it is ready to use for your yummies.
Notes
The dough which you make should be very soft and slightly sticky before the first rise, once it is risen then add more more and knead to a soft dough. This ensures that the pizza base turn crispy and chewy.
You can refrigerate the dough for a week. And use whenever you need. But make sure you use a big bowl or container, because they do rise in the fridge.
You can use other oil or butter in the dough. But in my opinion olive oil gives the real flavour.
