Combine the yeast and the warm water until thoroughly mixed. Put the remaining dry ingredients in a large bowl, make a well then pour in the water and oil (once cooled).
Mix together until you have a rough dough then turn out on to the counter. Flour the surface if needed then knead the dough until smooth and silky.
Place the dough in a large bowl, cover with cling film and a clean tea towel then leave for around an hour until it doubles in size.
