The perfect way to measure flour is on a scale but cups of flour will work just as well for this recipe. Do not use hot water, to make sure the water is lukewarm, It will kill the yeast. I use half cold and half warm to make lukewarm water. The best way to create a good rise is to place the dough in an airtight container or cover it with plastic wrap tightly. To score the top of the bread, use a sharp knife or a razor blade which is what bakers use to design the top of loaves.
