1: Measure all dry ingredients into a large bowl and mix together well. 2: Add the water and oil and bring the mixture together into a dough. 3: Knead (by hand or with mixer) until the dough is soft and no longer sticky to the touch. This takes about 10 minutes by machine or slightly longer by hand. Once you can stretch the dough and see light through it without it tearing the dough is ready. 4: Form the dough into a ball, cover with cling film or a plastic bag and leave to rise in a warm place for an hour or until the dough has doubled in size. 5: Using your fingers, prod the risen dough to remove most of the air, then roll into a long sausage shape. 6: Tear or cut the dough into regular-sized pieces, anything from 25-65g, depending upon your preference. 7: Using a cupped hand, place it over each ball of dough and roll in a circular motion to form smooth balls, using the thumb of that hand to tuck the dough under on each roll. 8: Once finished, starting with the first ball rolled, flatten between your palms then roll using a rolling pin or pasta roller on the widest setting to make flattened oval shapes. 9: Using a pastry brush or your fingers brush a little oil on one side of the oval then fold in half gently. 10: Place each oval on a small square of greaseproof paper then cover and leave to rise again for about 15 minutes or until doubled in size again. 11: Place in the basket of a steamer (making sure the water is at a rolling boil) and steam for seven-10 minutes. 12: Once steamed, the buns can be refrigerated, frozen or stored at room temperature, then re-steamed for a few minutes to heat through.
