• Add all the ingredients [except water and butter] to the sponge dough.  Knead till well combined, then gradually add in water while kneading till a soft dough is formed [you may not need all the water].  Knead for about 10 minutes then add in butter.  Continue kneading till soft, smooth and elastic.
