After creating
the sponge and allowing it to rise by at least a third the next step is to add the strong flour, salt, sugar
and cold milk to it. The softened butter is also added by rubbing it in a little at a time between the finger tips. You
continue to mix until a rough dough is formed.
Take the dough to a floured work surface and knead for 10 minutes... it seems an age so put on some music! The dough needs to be very soft and pliable at the stage. Cover the dough with cling film - leaving it on the work surface for about an hour.
